Introduction Thank you for your purchase of the Weather WH2902 WiFi OSPREY Solar Powered Wireless Weather Station. The following user guide provides step by step instructions for installation, operation and troubleshooting. 2. Warnings and Cautions Warning: Any metal object may attract a lightning strike, including your weather station mounting pole. Never install the weather station in a storm. Warning: Installing your weather station in a high location may result in injury or death. Perform as much of the initial check out and operation on the ground and inside a building or home. Only install the weather station on a clear, dry day. 3. Quick Start Guide Although the manual is comprehensive, much of the information contained may be intuitive. In addition, the manual does not flow properly because the sections are organized by components. The following Quick Start Guide provides only the necessary steps to install, operate the weather station, and upload to the internet, along with references to the pertinent sections.
Version 1.0 Page 3 Required Step Description Section 1 Assemble and power up the sensor array 5.3 3 Power up the display console and synchronize with sensor array 5.6 6 Mount the sensor array 5.3.5 4 Set date and time on console 6.3 5 Calibrate the relative pressure to sea-level conditions (local airport) on console 6.3 7 Reset the rain to zero on console 6.5.2 Optional 8 Configure WiFi 7.1 9 Register and upload to Weather Servers 7.1 and 8 4. Pre-Installation Checkout and Site Survey 4.1 Pre Installation Checkout Before installing your weather station in the permanent location, we recommend operating the weather station for one week in a temporary location with easy access. This will allow you to check out all of the functions, insure proper operation, and familiarize you with the weather station and calibration procedures. This will also allow you to test the wireless range of the weather station. 4.2 Site Survey Perform a site survey before installing the weather station. Consider the following: 1. You must clean the rain gauge every few months and change the rechargeable batteries every 2-3 years. Provide easy access to the weather station. 2. Avoid radiant heat transfer from buildings and structures. In general, install the sensor array at least 5’ from any building, structure, ground, or roof top. 3. Avoid wind and rain obstructions. The rule of thumb is to install the sensor array at least four times the distance of the height of the tallest obstruction. For example, if the building is 20’ tall, and the mounting pole is 6’ tall, install 4 x (20 – 6)’ = 56’ away. 4. Wireless Range. The radio communication between receiver and transmitter in an open field can reach a distance of up to 330 feet, providing there are no interfering obstacles such as buildings, trees, vehicles, high voltage lines. Wireless signals will not penetrate metal buildings. Under most conditions, the maximum wireless range is 100’. 5. Radio interference such as PCs, radios or TV sets can, in the worst case, entirely cut off radio communication. Please take this into consideration when choosing console or mounting locations. Make sure your display console is at least five feet away from any electronic device to avoid interference. 5. Getting Started The weather station consists of a display console (receiver), an all in one sensor array, and wireless thermo-hygrometer-barometer. 5.1 Parts List QTY Item

(b) tighten the set screw with a precision screw driver and make sure the wind vane spins freely. (a) (b) Figure 2 5.3.2 Install Wind Cups Reference Figure 3. (a) push the wind cups on to the shaft. (b) tighten the set screw with a precision screw driver and make sure the wind cups spin freely. (a) (b) Figure 3 5.3.3 Install the Rain Gauge Funnel Reference Figure 4. Install the rain gauge funnel. Rotate clockwise to attach the funnel to the sensor array.
Version 1.0 Page 6 Figure 4 5.3.4 Install Batteries Reference Figure 5. Insert 3 x AA non-rechargeable batteries (not included) into the battery compartment. The LED indicator on the back of the transmitter will turn on for four seconds, and then flash once every 16 seconds (the sensor transmission update period). (a) (b) Figure 5 Note: If the LED does not light up, or stays on permanently, make sure the battery polarity is correct, or the batteries are fresh. Do not install the batteries backwards. You can permanently damage the thermo-hygrometer. Note: We recommend lithium batteries for cold weather climates, but alkaline batteries are sufficient for most climates. We do not recommend rechargeable batteries. They have lower voltages, do not operate well at wide temperature ranges, and do not last as long, resulting in poorer reception.
Version 1.0 Page 7 5.3.5 Install Mounting Pole Reference Figure 6. The mounting assembly includes two U-Bolts and a bracket that tightens around a 1 to 2” diameter pole (not included) using the four U-Bolt nuts. (a) (b) Figure 6 Use the bubble level next to the rain sensor to make sure the sensor array is completely level. If the sensor array is not level, the rain gauge will not measure properly. 5.3.5.1 Aligning the Wind Direction Locate the four wind vane compass rose indicators of N, E, S, W (representing North, East, South and West) at the base of the wind vane. Align the compass rose direction upon final installation with a compass or GPS. 5.5 Best Practices for Wireless Communication Note: To insure proper communication, mount the remote sensor(s) upright on a vertical surface, such as a wall. Do not lay the sensor flat. Wireless communication is susceptible to interference, distance, walls and metal barriers. We recommend the following best practices for trouble free wireless communication. 1. Electro-Magnetic Interference (EMI). Keep the console several feet away from computer monitors and TVs. 2. Radio Frequency Interference (RFI). If you have other 915 MHz devices and communication is intermittent, try turning off these other devices for troubleshooting purposes. You may need to relocate the transmitters or receivers to avoid intermittent communication. 3. Line of Sight Rating. This device is rated at 300 feet line of sight (no interference, barriers or walls) but typically you will get 100 feet maximum under most real-world installations, which include passing through barriers or walls. 4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum siding. If you have metal siding, align the remote and console through a window to get a clear line of sight.

Absolute pressure is the measured atmospheric pressure, and is a function of altitude, and to a lesser extent, changes in weather conditions. Absolute pressure is not corrected to sea-level conditions. Relative pressure is corrected to sea-level conditions. For further discussion of relative pressure and calibration, reference Section 6.4.4. 6.4.2 Rate of Change of Pressure Graph The rate of change of pressure graphic is shown to the left of the barometric pressure and signifies the difference between the daily average pressure and the 30 day average (in hPa).
Version 1.0 Page 16 Figure 15 6.4.3 Viewing Pressure History Press the [PRESSURE -] button to view the 12 hour, 24 hour, 48 hour and 72 hour pressure average. 6.4.4 Relative Pressure Calibration Discussion To compare pressure conditions from one location to another, meteorologists correct pressure to sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected pressure (the pressure your location would be at if located at sea-level) is generally higher than your measured pressure. Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305 m), but the relative pressure is 30.00 inHg (1016 mb). The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the average sea-level pressure around the world. Relative pressure measurements greater than 29.92 inHg (1013 mb) are considered high pressure and relative pressure measurements less than 29.92 inHg are considered low pressure. To determine the relative pressure for your location, locate an official reporting station near you (the internet is the best source for real time barometer conditions, such as Weather.com or Wunderground.com), and set your weather station to match the official reporting station. 6.5 Rain Display 6.5.1 Rain Increments of Measure Press the RAIN button to switch between Rain Rate (in/hr), Rain Event, Rain Day, Rain Week, Rain Month, and Rain Total. 6.5.2 Resetting Rain To reset the rain totals, press and hold the RAIN button for two seconds.  Resetting the weekly rain also resets the daily rain.  Resetting the monthly rain also resets the daily and weekly rain.
Version 1.0 Page 17  Resetting the total rain also resets the monthly, weekly and daily rain. 6.5.3 Increments of Rain Definitions  Rain rate is defined as the last 10 minutes of rainfall, multiplied by six (10 minutes x 6 = 1 hour). This is also referred to as instantaneous rain per hour.  Rain event is defined as continuous rain, and resets to zero if rainfall accumulation is less than 10 mm (0.039 in) in a 24 hour period.  Daily Rain is defined as the rainfall since midnight (00:00).  Weekly Rain is defined as the calendar week total, and resets on Sunday morning at midnight (Sunday thru Saturday).  Monthly Rain is defined as the calendar month total, and resets on the first day of the Month.  Total Rain is defined as the running total since station was powered up. 6.6 Wind Display Press the [WIND +] button to switch between average wind speed, wind gust and wind direction.  Wind speed is defined as the average wind speed in the 16 second update period.  Wind gust is defined as the peak wind speed in the 16 second update period. 6.7 Temperature Display If temperature is lower than minimum range, the temperature field will display dashes (--.-).

Errors can occur due to electronic variation (example, the temperature sensor is a resistive thermal device or RTD, the humidity sensor is a capacitance device), mechanical variation, or degradation (wearing of moving parts, contamination of sensors). Calibration is only useful if you have a known calibrated source you can compare it against, and is optional. This section discusses practices, procedures and sources for sensor calibration to reduce manufacturing and degradation errors. Do not compare your readings obtained from sources such as the internet, radio, television or newspapers. The purpose of your weather station is to measure conditions of your surroundings, which vary significantly from location to location. Parameter Type of Calibration Default Typical Calibration Source Temperature Offset Current Value Red Spirit or Mercury Thermometer (1) Humidity Offset Current Value Sling Psychrometer (2) ABS Barometer Offset Current Value Calibrated laboratory grade barometer REL Barometer Offset Current Value Local airport (3) Wind Direction Offset Current Value GPS, Compass (4) Wind Gain 1.00 Calibrated laboratory grade wind meter (5) Rain Gain 1.00 Sight glass rain gauge with an aperture of at least 4” (6) Figure 22 (1) Temperature errors can occur when a sensor is placed too close to a heat source (such as a building structure, the ground or trees). To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer. Bi-metal (dial) and digital thermometers (from other weather stations) are not a good source and have their own margin of error. Using a local weather station in your area is also a poor source due to changes in location, timing (airport weather stations are only updated once per hour) and possible calibration errors (many official weather stations are not properly installed and calibrated). Place the sensor in a shaded, controlled environment next to the fluid thermometer, and allow the sensor to stabilize for 48 hours. Compare this temperature to the fluid thermometer and adjust the console to match the fluid thermometer.
Version 1.0 Page 25 (2) Humidity is a difficult parameter to measure electronically and drifts over time due to contamination. In addition, location has an adverse affect on humidity readings (installation over dirt vs. lawn for example). Official stations recalibrate or replace humidity sensors on a yearly basis. Due to manufacturing tolerances, the humidity is accurate to ± 5%. To improve this accuracy, the indoor and outdoor humidity can be calibrated using an accurate source, such as a sling psychrometer. (3) The display console displays two different pressures: absolute (measured) and relative (corrected to sea-level). To compare pressure conditions from one location to another, meteorologists correct pressure to sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected pressure (the pressure your location would be at if located at sea-level) is generally higher than your measured pressure. Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305 m), but the relative pressure is 30.00 inHg (1016 mb). The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the average sea-level pressure around the world. Relative pressure measurements greater than 29.92 inHg (1013 mb) are considered high pressure and relative pressure measurements less than 29.92 inHg are considered low pressure. To determine the relative pressure for your location, locate an official reporting station near you (the internet is the best source for real time barometer conditions, such as Weather.com or Wunderground.com), and set your weather station to match the official reporting station. (4) Only use this if you improperly installed the weather station sensor array, and did not point the direction reference to true north. (5) Wind speed is the most sensitive to installation constraints. The rule of thumb for properly installing a wind speed sensor is 4 x the distance of the tallest obstruction. For example, if your house is 20’ tall and you mount the sensor on a 5’ pole: Distance = 4 x (20 – 5)’ = 60’. Many installations are not perfect and installing the weather station on a roof can be difficult. Thus, you can calibrate for this error with a wind speed multiplier. In addition to the installation challenges, wind cup bearings (moving parts) wear over time. Without a calibrated source, wind speed can be difficult to measure. We recommend using a calibrated wind meter and a constant speed, high speed fan. (6) The rain collector is calibrated at the factory based on the funnel diameter. The bucket tips every 0.01” of rain (referred to as resolution). The accumulated rainfall can be compared to a sight glass rain gauge with an aperture of at least 4”. Make sure you periodically clean the rain gauge funnel.

Remove the power from the console by removing the batteries and disconnecting the AC adapter. 2. Apply power by connecting the AC adapter. 3. Wait for all of the segments to appear on the screen, as shown in Figure 11. 4. Press and hold the WIND/+ and PRESSURE/- buttons at the same time until the console power up sequence is complete (about 5 seconds). 5. Replace the batteries. 6.12 Resynchronize Wireless Sensor Press and hold the LIGHT /SNOOZE button for 5 seconds, and the console will re-register the wireless sensor. 6.13 Backlight Operation 6.13.1 With AC Adapter The backlight can only be continuously on when the AC adapter is permanently on. When the AC adapter is disconnected, the backlight can be temporarily turned on. Press the LIGHT SNOOZE button to adjust the brightness between High, Low and Off. 6.13.2 Without AC Adapter To reduce power consumption, the console will sleep on battery power only, and will not send data to the Internet. To temporarily turn on the back light for 15 seconds, press the LIGHT SNOOZE button. 6.14 Tendency Arrows Tendency arrows allow you to quickly determine of temperature or pressure are rising and falling in a three hour update period, updated every 30 minutes. Figure 23 defines the conditions for rising and falling pressure every 3 hours. Tendency indicators Condition Humidity Change per 3 Hours Temperature Change per 3 Hours Rising Rising > 3% Rising > 1º C / 2 ºF Steady Change ≤ ±3% Change ≤ ± 1 º C / 2 º F Falling Falling > 3% Falling > 1º C / 2 ºF Figure 23 6.15 Wireless Signal Strength Indicator The wireless signal strength displays reception quality. If no signal is lost, the signal strength indicator will display 5 bars. If the signal is lost once, four bars will be displayed, a shown in Figure 24. Five Bars Four Bars
Version 1.0 Page 27 No signal loss Lost signal once Figure 24 6.16 Weather Forecasting The five weather icons are Sunny, Partly Cloudy, Cloudy, Rainy and Stormy. The forecast icon is based on the rate of change of barometric pressure. Please allow at least one month for the weather station to learn the barometric pressure over time. Sunny Partly Cloudy Cloudy Rainy Stormy Snowy Pressure increses for a sustained period of time Pressure increases slightly, or initial power up Pressure decreases slightly Pressure decreases for a sustained period of time Pressure rapidly decreases Pressure decreases for a sustained period of time and temperature is below freezing Figure 25 6.16.1 Weather Forecasting Description and Limitations In general, if the rate of change of pressure increases, the weather is generally improving (sunny to partly cloudy). If the rate of change of pressure decreases, the weather is generally degrading (cloudy, rainy or stormy). If the rate of change is relatively steady, it will read partly cloudy. The reason the current conditions do not match the forecast icon is because the forecast is a prediction 24-48 hours in advance. In most locations, this prediction is only 70% accurate and it is a good idea to consult the National Weather Service for more accurate weather forecasts. In some locations, this prediction may be less or more accurate. However, it is still an interesting educational tool for learning why the weather changes. The National Weather Service (and other weather services such as Accuweather and The Weather Channel) have many tools at their disposal to predict weather conditions, including weather radar, weather models, and detailed mapping of ground conditions.

Glossary of Terms Term Definition Absolute Barometric Pressure Absolute pressure is the measured atmospheric pressure and is a function of altitude, and to a lesser extent, changes in weather conditions. Absolute pressure is not corrected to sea-level conditions. Refer to Relative Barometric Pressure.
Version 1.0 Page 37 Term Definition Accuracy Accuracy is defined as the ability of a measurement to match the actual value of the quantity being measured. Barometer A barometer is an instrument used to measure atmospheric pressure. Calibration Calibration is a comparison between measurements – one of known magnitude or correctness of one device (standard) and another measurement made in as similar a way as possible with a second device (instrument). Dew Point The dew point is the temperature at which a given parcel of humid air must be cooled, at constant barometric pressure, for water vapor to condense into water. The condensed water is called dew. The dew point is a saturation temperature. The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and the air is maximally saturated with water. When the dew point remains constant and temperature increases, relative humidity will decrease. Heat Index The Heat Index, sometimes referred to as the apparent temperature, is a measure of how hot it really feels when relative humidity is factored with the actual air temperature. To find the Heat Index temperature, look at the Heat Index chart below. As an example, if the air temperature is 96°F and the relative humidity is 65%, the heat index (how hot it feels) is 121°F. IMPORTANT: Since heat index values were devised for shady, light wind conditions, exposure to full sunshine can increase heat index values by up to 15°F. Also, strong winds, particularly with very hot, dry air, can be extremely hazardous. The Heat Index Chart shaded zone above 105°F shows a level that may cause increasingly severe heat disorders with continued exposure or physical activity. Heat Index is not calculated below 80°F. HectoPascals (hPa) Pressure units in SI (international system) units of measurement. Same as millibars (1 hPa = 1 mbar)
Version 1.0 Page 38 Term Definition Hygrometer A hygrometer is a device that measures relative humidity. Relative humidity is a term used to describe the amount or percentage of water vapor that exists in air. Inches of Mercury (inHg) Pressure in Imperial units of measure. 1 inch of mercury = 33.86 millibars Rain Gauge A rain gauge is a device that measures liquid precipitation (rain), as opposed to solid precipitation (snow gauge) over a set period of time. All digital rain gauges are self emptying or self dumping (also referred to as tipping rain gauge). The precision of the rain gauge is based on the volume of rain per emptying cycle. Range Range is defined as the amount or extent a value can be measured. Relative Barometric Pressure Measured barometric pressure relative to your location or ambient conditions. Resolution Resolution is defined as the number of significant digits (decimal places) to which a value is being reliably measured. Solar Radiation A solar radiation sensor measures solar energy from the sun. Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. The spectrum of solar radiation is close to that of a black body with a temperature of about 5800 K. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum. Thermometer A thermometer is a device that measures temperature. Most digital thermometers are resistive thermal devices (RTD). RTDs predict change in temperature as a function of electrical resistance. Wind Vane A wind vane is a device that measures the direction of the wind. The wind vane is usually combined with the anemometer. Wind direction is the direction from which the wind is blowing. 10.

Maintenance 1. Clean the rain gauge once every 3 months. Rotate the funnel counter-clockwise and lift to expose the rain gauge mechanism, and clean with a damp cloth. Remove any dirt, debris and insects. If bug infestation is an issue, spray the array lightly with insecticide. Figure 38 2. Clean the solar radiation sensor and solar panel every 3 months with damp cloth. 3. Replace batteries every 1-2 years. If left in too long, the batteries may leak due to
Version 1.0 Page 40 environmental challenges. 4. In snowy environments, spray the top of the weather station with anti-icing silicon spray to prevent snow build up. 12. Troubleshooting Guide Problem Solution Outdoor sensor array does not communicate to the display console. The sensor array may have initiated properly and the data is registered by the console as invalid, and the console must be reset. Press the reset button as described in Figure 1. With an open ended paperclip, press the reset button for 3 seconds to completely discharge the voltage. Take out the batteries and wait one minute, while covering the solar panel to drain the voltage. Put batteries back in and resync the console (Section 6.12) with the sensor array about 10 feet away. The LED next to the battery compartment will flash every 16 seconds. If the LED is not flashing every 16 seconds… Replace the batteries in the outside sensor array. If the batteries were recently replaced, check the polarity. If the sensor is flashing every 16 seconds, proceed to the next step. There may be a temporary loss of communication due to reception loss related to interference or other location factors, or the batteries may have been changed in the sensor array and the console has not been reset. The solution may be as simple as powering down and up the console (remove AC power and batteries, wait 10 seconds, and reinsert AC power and batteries). Temperature sensor reads too high in the day time. Make certain that the sensor array is not too close to heat generating sources or strictures, such as buildings, pavement, walls or air conditioning units. Use the calibration feature to offset installation issues related to radiant heat sources. Reference Section 6.10. Relative pressure does not agree with official reporting station You may be viewing the absolute pressure, not the relative pressure. Select the relative pressure. Make sure you properly calibrate the sensor to an official local weather station. Reference Section 6.4 for details. Rain gauge reports rain when it is not raining An unstable mounting solution (sway in the mounting pole) may result in the tipping bucket incorrectly incrementing rainfall. Make sure you have a stable, level mounting solution. Data not reporting to Wunderground.com 1. Confirm your password or key is correct. It is the password you registered on Wunderground.com. Your Wunderground.com password cannot begin with a non-alphanumeric character (a limitation of Wundeground.com, not the station). Example, $oewkrf is not a valid password, but oewkrf$ is valid.
Version 1.0 Page 41 Problem Solution 2. Confirm your station ID is correct. The station ID is all caps, and the most common issue is substituting an O for a 0 (or visa versa). Example, KAZPHOEN11, not KAZPH0EN11 3. Make sure the date and time is correct on the console. If incorrect, you may be reporting old data, not real time data. 4. Make sure your time zone is set properly. If incorrect, you may be reporting old data, not real time data. 5. Check your router firewall settings. The console sends data via Port 80. No WiFi connection 1. Check for WiFi symbol on the display. If wireless connectivity is successful the WiFi icon will be displayed in the time field. 2. Make sure your modem WiFi settings are correct (network name, and password). 13.
