HOBO® MX2300 Series Data Logger Manual 20923-1 The HOBO MX2300 series data loggers record and transmit temperature and/or relative humidity (RH) in outdoor environments. These Bluetooth® Low Energy-enabled loggers are designed for wireless communication with a mobile device. Using the HOBOmobile® app, you can easily configure the logger, read it out, and view data on your phone or tablet, or export the data for further analysis. The logger can calculate minimum, maximum, average, and standard deviation statistics and be configured to trip alarms at thresholds you specify. The logger also supports burst logging in which data is logged at a different interval when sensor readings are above or below certain limits. The Temp and Temp/RH models have internal sensors while the External Temp/RH, External Temp, and 2x External Temp include built-in external sensors, offering a wide range of solutions for monitoring outdoor temperature and RH.

If the logger does not appear in the list or if it is having trouble connecting, follow these tips: • Make sure the logger is “awake” by pressing the start button. The alarm and status LEDs will blink once when the logger wakes up. You can also press the button a second time to bring it to the top of the list if you are working with multiple loggers. • Make sure the logger is within range of your mobile device. The range for successful wireless communication is approximately 30.5 m (100 ft) with full line-of-sight. • If your device can connect to the logger intermittently or loses its connection, move closer to the logger, within sight if possible. • If the logger appears in the list, but you cannot connect to it, close HOBOmobile and power cycle the mobile device. This forces the previous Bluetooth connection to close. Once connected to the logger you can select one of the following actions: • Configure. Select logger settings and load them onto the logger to start logging. See Configuring the Logger. • Readout. Download logger data. See Reading Out the Logger. • Full Status Details. Check the battery level and view the configuration settings currently selected for the logger. • Start Logging. Select this option to begin logging (if the logger is configured to start “On Button Push” as described in Configuring the Logger). • Stop Logging. Stop the logger from recording data. This overrides any Stop Logging settings described in Configuring the Logger. • Page Logger LED. Press and hold this option to illuminate the alarm and status LEDs for 4 seconds. • Logger Password. Select this to create a password for the logger that will be required if another mobile device attempts to connect to it. To reset a password, connect to the logger, tap Set Logger Passkey, and select Reset to Factory Default. You can also press the button on the logger for 10 seconds to reset a password. • Update Firmware. When new logger firmware is available, this action appears in the list. Select it and follow the instructions on the screen. Note that if there is a communication failure during the firmware update process, the logger will revert to the previous firmware. Important: Before updating the firmware on the logger, always read out the logger first. Check the remaining battery level by selecting Full Status Details and make sure it is no less than 30%. Make sure you have the time to complete the entire update process, which requires that the logger remains connected to the device during the upgrade. • Force Offload. This may appear if an error was encountered when loading configure settings. Select this to offload all the data on the logger before reconfiguring the logger. Configuring the Logger Use HOBOmobile to set up the logger, including selecting the logging options, configuring alarms, and enabling Power Saving Mode. These steps provide an overview of setting up the logger. For complete details, see the HOBOmobile User’s Guide. 1. Press the button on the logger to wake it up. 2. Find the logger in the list and tap it to connect to it. If you are working with multiple loggers, you can press the button on the logger a second time to bring it to the top of the list. The logger name (or serial number if no name has been assigned) turns green when the logger moves to the top of the list. Note that the current readings are displayed even when the logger is not logging. 3. Once connected, tap Configure. 4. Tap Name and type a name for the logger up to 20 characters (optional). Tap Done. If no name is selected, the logger serial number is used as the name. 5. Tap Group to add the logger to the Favorites group, an existing custom group, or create a new group name with up to 20 characters (optional). Tap Done. 6. Tap Logging Interval and choose how frequently the logger will record data unless operating in burst logging mode (see Burst Logging). 7. Tap Start Logging and select when logging will begin: • Now. Logging will begin immediately after tapping Start in the Configure screen. PLACEHOLDER PLACEHOLDER PLACEHOLDER
HOBO MX2300 Series Data Logger Manual 1-800-LOGGERS 4 www.onsetcomp.com • On Next Logging Interval. Logging will begin at the next even interval as determined by the selected logging interval. • On Button Push. Logging will begin once you press the button on the logger for 4 seconds. • On Date/Time. Logging will begin on a date and time you specify. Select the Date and time and tap Done. Tap Done in the Start Logging screen. 8. Tap Stop Logging and select the options for when logging will end. a. Choose one of two memory options: • When Memory Fills. The logger will continue recording data until the memory is full. • Never (Wrap When Full). The logger will continue recording data indefinitely, with newest data overwriting the oldest. This option is not available if the Logging Mode is set to Burst (see Burst Logging). b. Select On Button Push if you want to be able to stop logging by pushing the button on the logger for 4 seconds. Note that if you also choose On Button Push for the Start Logging option, then you will not be able to stop logging until 30 seconds after logging begins. If you select On Button Push for the Stop Logging option, then you also have the option to select Allow Button Restart. This allows you to stop and then resume logging during the deployment by pushing the Start/Stop button on the logger for 3 seconds. Important: When Allow Button Restart is selected and you use the Start/Stop button to stop and restart logging, logging will restart on the next even logging interval, not at the time the button was pushed. For example, a logger started logging at 7:00 AM with a logging interval set to 1 hour. If you press the Start/Stop button to stop the logger at 8:45 AM and then press the button again at 10:15 AM, logging will not begin immediately at 10:15 AM. Instead, logging will begin again at 11:00 AM, which is the next even interval time based on your 1-hour logging interval. Therefore, depending on the logging interval, the gap between the time you press the button to resume logging and the time actual logging begins could be significant. The faster the logging interval, the less time will elapse before logging resumes. c. Select one of the following time options for when to stop logging: • Never. Select this if you do not want the logger to stop at any predetermined time frame. • On Date/Time. Select this if you want the logger to stop logging on a specific date and time. Select the date and time and then tap Done. • After. Select this if you want to control how long the logger should continue logging once it starts. Choose the amount of time you want the logger to log data and then tap Done. For example, select 30 days if you want the logger to log data for 30 days after logging begins. d. Tap Done in the Stop Logging screen. 9. Select the sensor measurement types that will be logged. Both the temperature and RH sensors are required to calculate dew point, which is an additional data series available for plotting after reading out the logger. You can also set up alarms to trip when a sensor reading rises above or falls below a specified value. See Setting up Alarms for details on enabling sensor alarms. 10. Tap Logging Mode. Select either fixed interval logging or burst logging. With fixed interval logging, the logger records data for all enabled sensors and/or selected statistics at the logging interval selected (see Statistics Logging for details on choosing statistics options). In burst mode, logging occurs at a different interval when a specified condition is met. See Burst Logging for more information. Tap Done. 11. Enable or disable Show LED. If Show LED is disabled, the alarm and status LEDs on the logger will not be illuminated while logging (the alarm LED will not blink if an alarm trips). You can temporarily turn on LEDs when Show LED is disabled by pressing the button on the logger for 1 second. 12. Enable or disable Power Saving Mode. If Power Saving Mode is disabled, the logger will “advertise” or regularly send out a Bluetooth signal for the phone or tablet to find via HOBOmobile while it is logging, which uses battery power. When Power Saving Mode is enabled, the logger will only advertise during logging when you press the button on the logger to wake it up, thereby preserving as much battery power as possible. 13. Tap Start in the upper right corner of the Configure screen to load the settings onto the logger. Logging will begin based on the settings you selected. See Deploying the Logger for details on mounting and see Reading Out the Logger for details on downloading. Setting up Alarms You can set an alarm to trip on the logger when a sensor reading rises above or falls below a specified value. This can alert you to problems so you can take corrective action. To set an alarm: 1. Tap the HOBOs icon and tap the logger to connect to it. If the logger was configured with Power Saving Mode enabled, press the button on the logger to wake it up. When working with multiple loggers, you can also press the button on the logger to bring it to the top of the list. 2. Once connected, tap Configure. 3. In Sensor & Alarm Setup, tap an enabled sensor. 4. Enable the High Alarm if you want an alarm to trip when the sensor reading rises above the high alarm value. Drag the slider to the reading that will trip the alarm or tap the value field and type a specific reading. In the following example, an alarm will trip when the temperature rises above 85°F. PLACEHOLDER
HOBO MX2300 Series Data Logger Manual 1-800-LOGGERS 5 www.onsetcomp.com 5. Enable the Low Alarm if you want an alarm to trip when the sensor reading falls below the low alarm value. Drag the slider to the reading that will trip the alarm or tap the value field and type a specific reading. In the example, an alarm is configured to trip when the temperature falls below 32°F. Note: The actual values for the high and low alarm limits are set to the closest value supported by the logger. 6. Under Raise Alarm After, select the duration before an alarm is tripped and tap Done in the Alarm Duration screen. 7. Select either Cumulative or Consecutive Samples. If you select Cumulative Samples, then the alarm will trip when the time the sensor is out of range over the course of the deployment is equal to the selected duration. If you select Consecutive Samples, then the alarm will trip when the time the sensor is continuously out of range is equal to the selected duration. For example, the high alarm for temperature is set to 85°F and the duration is set to 30 minutes. If Cumulative is selected, then an alarm will trip once a sensor reading has been at or above 85°F for a total of 30 minutes since the logger was configured; specifically, this could be 15 minutes above 85°F in the morning and then 15 minutes above 85°F again in the afternoon. If Consecutive is selected, then an alarm will trip only if all sensor readings are 85°F or above for a continuous 30-minute period. 8. Tap Done and repeat steps 3–8 for the other sensor if desired. 9. Back in the Configure screen, a setting to maintain the alarm until the logger is reconfigured is enabled automatically. This cannot be disabled. 10. Tap Start in the Configure screen to load the alarm settings onto the logger if you are ready to start. When an alarm trips, the logger alarm LED blinks every 4 seconds (unless Show LED is disabled), an alarm icon appears in the app, and an Alarm Out of Range event is logged. Even if the reading returns to a normal range, the alarm indicator will not clear in the app and the alarm LED will continue to blink. Notes: • Alarms are checked <placeholder>. • The actual values for the high and low alarm limits are set to the closest value supported by the logger. For example, the closest value to 85°F that the logger can record is 84.990°F and the closest value to 32°F is 32.043°F. In addition, alarms can trip or clear when the sensor reading is within the logger specifications of 0.04°C resolution. This means the value that triggers the alarm may differ slightly than the value entered. For example, if the High Alarm is set to 75.999°F, the alarm can trip when the sensor reading is 75.994°F (which is within the 0.04°C resolution). • When you read out the logger, alarm events can be displayed on the plot or in the data file. See Logger Events. • If the logger was configured to stop logging with a button push, any tripped alarms will be cleared automatically when logging is stopped and no Alarm Cleared event will be logged in the data file. This ensures that the logger will start checking for alarm conditions when logging resumes (if the logger was configured with Allow Button Restart selected). Burst Logging Burst logging is a logging mode that allows you to set up more frequent logging when a specified condition is met. For example, a logger is recording data at a 5-minute logging interval and burst logging is configured to log every 30 seconds when the temperature rises above 85°F (the high limit) or falls below 32°F (the low limit). This means the logger will record data every 5 minutes as long as the temperature remains between 85°F and 32°F. Once the temperature rises above 85°F, the logger will switch to the faster logging rate and record data every 30 seconds until the temperature falls back to 85°F. At that time, logging then resumes every 5 minutes at the normal logging interval. Similarly, if the temperature falls below 32°F, then the logger would switch to burst logging mode again and record data every 30 seconds. Once the temperature rises back to 32°F, the logger will then return to normal mode, logging every 5 minutes. Note: Sensor alarms, statistics, and the Stop Logging option “Wrap When Full” are not available in burst logging mode. To set up burst logging: 1. Tap the HOBOs icon and tap the logger to connect to it. If the logger was configured with Power Saving Mode enabled, press the button on the logger to wake it up. When working with multiple loggers, you can also press the button on the logger to bring it to the top of the list. 2. Once connected, tap Configure. 3. Tap Logging Mode and then tap Burst Logging. 4. Tap a sensor under Burst Sensor Limits. 5. Enable High Limit if you want burst logging to occur when the sensor reading rises above a specific reading. Drag the slider to the reading that will trigger burst logging or tap the value field and type a specific reading. In this example, the logger will switch to burst logging when the temperature rises above 85°F.
HOBO MX2300 Series Data Logger Manual 1-800-LOGGERS 6 www.onsetcomp.com 6. Enable Low Limit if you want burst logging to occur when the sensor reading falls below a specific reading. Drag the slider to the reading that will trigger burst logging or tap the value field and type a specific reading. In the example, the logger will switch to burst logging when the temperature falls below 32°F. 7. Tap Done and repeat steps 4–7 for the other sensor if desired. 8. Tap Burst Logging Interval and select an interval faster than the logging interval. Keep in mind that the more frequent the burst logging rate, the greater the impact on battery life and the shorter the logging duration. Tap Done. 9. Tap Done to exit the Logging Mode screen. 10. Tap Start in the Configure screen to load the burst settings onto the logger if you are ready to start. Notes: • Burst limits are checked <placeholder>. • If high and/or low limits have been configured for more than one sensor, then burst logging will begin when any high or low condition goes out of range. Burst logging will not end until all conditions on all sensors are back within normal range. • The actual values for the burst logging limits are set to the closest value supported by the logger. For example, the closest value to 85°F that the logger can record is 84.990°F and the closest value to 32°F is 32.043°F. • Burst logging mode can begin or end when the sensor reading is within the logger specifications of 0.04°C resolution. This means the value that triggers burst logging may differ slightly than the value entered. For example, if the high limit for a temperature alarm is set to 75.999°F, burst logging can start when the sensor reading is 75.994°F (which is within the 0.04°C resolution). • Once the high or low condition clears, the logging interval time will be calculated using the last recorded data point in burst logging mode, not the last data point recorded in “normal mode.” For example, let’s assume the logger has a 10-minute logging interval and logged a data point at 9:05. Then, the high limit was surpassed and burst logging began at 9:06. Burst logging then continued until 9:12 when the sensor reading fell back below the high limit. Now back in normal mode, the next logging interval will be 10 minutes from the last burst logging point, or 9:22 in this case. If burst logging had not occurred, the next data point would have been at 9:15. • A New Interval event is created each time the logger enters or exits burst logging mode. See Logger Events for details on plotting and viewing the event. In addition, if the logger is stopped with a button push while in burst logging mode, then a New Interval event is automatically logged and the burst condition is cleared, even if the actual high or low condition has not cleared. The logger will check the high and low conditions when logging resumes (if the logger was configured with Allow Button Restart selected). Statistics Logging During fixed interval logging, the logger records data for enabled sensors and/or selected statistics at the logging interval selected. Statistics are calculated at a sampling rate you specify with the results for the sampling period recorded at each logging interval. The following statistics can be logged for each sensor: • The maximum, or highest, sampled value, • The minimum, or lowest, sampled value, • An average of all sampled values, and • The standard deviation from the average for all sampled values. For example, a logger is configured with both the temperature and RH sensors enabled, and the logging interval set to 5 minutes. The logging mode is set to fixed interval logging with Normal and all four statistics enabled and with a statistics sampling interval of 30 seconds. Once logging begins, the logger will measure and record the actual temperature and RH sensor values every 5 minutes. In addition, the logger will take a temperature and RH sample every 30 seconds and temporarily store them in memory. The logger will then calculate the maximum, minimum, average, and standard deviation using the samples gathered over the previous 5-minute period and log the resulting values. When reading out the logger, this would result in 10 data series (not including any derived series, such as dew point): two sensor series (with temperature and RH data logged every 5 minutes) plus eight maximum, minimum, average, and standard deviation series (four for temperature and four for RH with values calculated and logged every 5 minutes based on the 30-second sampling). To log statistics: 1. Tap the HOBOs icon and tap the logger to connect to it. If the logger was configured with Power Saving Mode enabled, press the button on the logger to wake it up. When working with multiple loggers, you can also press the button on the logger to bring it to the top of the list. 2. Once connected, tap Configure. 3. Tap Logging Mode and then select Fixed Interval Logging. 4. Select Normal to record the current reading for each enabled sensor at the logging interval shown at the top of the screen. Do not select this if you only want to log statistics. 5. Select the statistics you want the logger to record at each logging interval: Maximum, Minimum, Average, and Standard Deviation (average is automatically enabled when selecting Standard Deviation). Statistics will be logged for all enabled sensors. In addition, the more statistics you record,
HOBO MX2300 Series Data Logger Manual 1-800-LOGGERS 7 www.onsetcomp.com the shorter the logger duration and the more memory is required. 6. Tap Statistics Sampling Interval and select the rate to use for calculating statistics. The rate must be less than, and a factor of, the logging interval. For example, if the logging interval is 1 minute and you select 5 seconds for the sampling rate, then the logger will take 12 sample readings between each logging interval (one sample every 5 seconds for a minute) and use the 12 samples to record the resulting statistics at each 1-minute logging interval. Note that the more frequent the sampling rate, the greater the impact on battery life. 7. Tap Done. 8. Tap Done again to exit the Logging Mode screen. 9. Tap Start in the Configure screen to load the statistics settings onto the logger if you are ready to start. Setting a Password You can create an encrypted password for the logger that will be required if another phone or tablet attempts to connect to it. This is recommended to ensure that a deployed logger is not mistakenly stopped or purposely altered by others. This password uses a proprietary encryption algorithm that changes with every connection. To set a password: 1. Tap the HOBOs icon and connect to the logger. 2. Tap Logger Password. 3. Type a password up to 10 characters. 4. Tap Save. Only the phone or tablet used to set the password can then connect to the logger without entering a password; all other mobile devices will be required to enter the password. For example, if you set the password for the logger with your tablet and then try to connect to the device later with your phone, you will be required to enter the password on the phone but not with your tablet. Similarly, if others attempt to connect to the logger with different devices, then they would also be required to enter the password. To reset a password, connect to the logger, tap Set Logger Passkey, and select Reset to Factory Default or press the button on the logger for 10 seconds. Reading Out the Logger To offload data from the logger: 1. Tap the HOBOs icon and tap the logger to connect to it. If the logger was configured with Power Saving Mode enabled, press the button on the logger to wake it up. When working with multiple loggers, you can also press the button on the logger to bring it to the top of the list. 2. Once connected, tap Readout. 3.

Select the events you wish to plot and then tap again. You can also view events in shared or exported data files. Internal Event Name Definition Host Connected The logger was connected to the mobile device. Started The Start button was pressed to begin or resume logging. Stopped The logger stopped logging. Alarm Out of Range/In Range An alarm has occurred because the reading was outside the alarm limits or back within range. Note: Although the reading may return to a normal range, the alarm indicator will not clear in the app and the alarm LED will continue to blink until you reconfigure the logger. New Interval The logger has entered or exited burst logging mode. Safe Shutdown The battery level dropped below 1.85 V; the logger performs a safe shutdown. Deploying and Mounting the Logger Follow these guidelines when deploying the logger: • A solar radiation shield is required if the MX2301 or MX2305 logger or the external sensors from an MX2302, MX2303, or MX2304 logger will be in sunlight at any time. • When using a solar radiation shield with an MX2301 or MX2305 model, the logger must be mounted horizontally using the solar radiation shield bracket (MX2300-RS-BRACKET) as shown below. For more details on the solar radiation shield, refer to the Solar Radiation Shield Installation Guide at www.onsetcomp.com/manuals/rs1.
HOBO MX2300 Series Data Logger Manual 1-800-LOGGERS 8 www.onsetcomp.com • When deploying an MX2302 logger, the sensor must be mounted vertically. If the sensor is being deployed in a solar radiation shield, mount it vertically as shown below. • When deploying a logger with external sensors (MX2302, MX2303, and MX2304), mount the logger so the sensor cable is not being pulled. Leave about 5 cm (2 in.) of drip loop in the cable where it comes out of the logger to prevent water from entering the logger housing. • For loggers with external sensors (MX2302, MX2303, and MX2304) or for MX2301 and MX2305 loggers that are not being deploying with a solar radiation shield, you can either use the included large screws or cable ties to mount the logger via the mounting holes. Use the screws to attach the logger to a wall or flat surface. Use the cable ties to affix the logger to a PVC pipe or mast. Protecting the Logger Note: Static electricity may cause the logger to stop logging. The logger has been tested to 8 KV, but avoid electrostatic discharge by grounding yourself to protect the logger. For more information, search for “static discharge” on onsetcomp.com. Battery Information The logger requires one user-replaceable 2/3 AA 3.6 V lithium battery. Battery life is 1 year, typical with a logging interval of 1 minute, but may be extended to 2 years when the logger is configured with Power Saving Mode enabled. Expected battery life varies based on the ambient temperature where the logger is deployed, the logging or sampling interval, frequency of offloading and connecting to the mobile device, number of channels that are active, and use of burst mode or statistics logging. Deployments in extremely cold or hot temperatures or logging interval faster than 1 minute can impact battery life. Estimates are not guaranteed due to uncertainties in initial battery conditions and operating environment. To install or replace the battery: 1. Use a Phillips-head screwdriver to unscrew the four screws from the back of the logger. 2. Carefully separate the top and bottom of the logger enclosure. 3. Remove the old battery and insert the new battery observing polarity. 4. Carefully reassemble the logger enclosure and screw in the four screws. WARNING: Do not cut open, incinerate, heat above 85°C (185°F), or recharge the lithium battery. The battery may explode if the logger is exposed to extreme heat or conditions that could damage or destroy the battery case. Do not dispose of the logger or battery in fire. Do not expose the contents of the batteries to water. Dispose of the battery according to local regulations for lithium batteries.
