3.3 Outdoor Thermo-Hygrometer Sensor Set Up
Note: To avoid permanent damage, please take note of the battery polarity before inserting the
batteries.
The outdoor thermometer-hygrometer measures and displays the outdoor temperature and humidity to
the ObserverIP receiver.
Version 1.0 Page 4
Remove the battery door on the back of the sensor by sliding off the battery door. Insert two AA
batteries as shown in Figure 1, and close the battery door. Note that the temperature and humidity
will be displayed on the LCD display.
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.
Figure 1
3.4 Mounting the Outdoor Thermo-Hygrometer Sensor
It is recommended you mount the remote sensor on a north facing wall, in a shaded area, at a height at
or above the receiver. Direct sunlight and radiant heat sources will result in inaccurate temperature
readings. Although the sensor is weatherproof, it is best to mount in a well protected area, such as an
eve.
Use a small nail or screw (included) to mount to a vertical surface, as shown in Figure 2.
Version 1.0 Page 5
Figure 2
The sensor can also be hung from a nylon zip tie (included) or string (not included).
Figure 3
3.5 Indoor Thermo-Hygrometer-Barometer Transmitter
The indoor thermometer, hygrometer and barometer measures and displays the indoor temperature,
humidity and pressure and transmits this data to the ObserverIP receiver.
Note: Do not install the thermo-hygrometer-barometer transmitter outside. This will cause errors
Version 1.0 Page 6
in the barometric pressure due to large variations in temperature (barometric pressure is temperature
compensated for accuracy). Note that pressure readings made inside your home, business, or facility
will correspond closely to the actual barometric pressure outside.
Note: The thermo-hygrometer-transmitter transmits directly to the ObserverIP receiver. For best
results, place between 5 to 20 feet from the ObserverIP receiver.
Note: To avoid permanent damage, please take note of the battery polarity before inserting the
batteries.
Remove the battery door on the back of the sensor by sliding off the battery door. Insert two AA
batteries as shown in Figure 1, and close the battery door. Note that the temperature, humidity and
barometer will be displayed on the LCD display.
3.5 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 ObserverIP receiver several feet away from
computer monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 433 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 ObserverIP receiver through a window
to get a clear line of sight.
The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction
decreases the transmission range by the factor shown below.
Medium RF Signal Strength Reduction
Glass (untreated) 5-15%
Plastics 10-15%
Wood 10-40%
Brick 10-40%
Concrete 40-80%
Metal 90-100%

3.9.6 Calibration
Select the Calibration tab to view your calibration data from the weather station. Select the Apply
button to confirm changes.
Calibration of most parameters is not required, with the exception of Relative Pressure, which must be

calibration, please reference note (3) below.
3.9.6.1 Relative Barometric Pressure Calibration Example
The following is an example of calibrating the relative pressure. Your results will vary.
1. The local relative pressure from TV, the newspaper or the internet for the official station in
your area is 30.12 inHg.
2. From the Live Data panel, your absolute pressure (measured, and not corrected to sea-level)
reads 28.90 inHg.
3. Reference Figure 21. Enter the following offset in the Calibration panel for Relative
Pressure Offset:
Relative Pressure Offset = 30.12 – 28.90 = 1.22

(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 ObserverIP receiver to match the fluid thermometer.
(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 ObserverIP receiver 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.
Version 1.0 Page 21
Note: The purpose of calibration is to fine tune or correct for any sensor error associated with the
devices margin of error. 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 (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.

5. 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.
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.
HectoPascals (hPa) Pressure units in SI (international system) units of measurement. Same

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
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.
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.

7. Troubleshooting Guide
Problem Solution
Wireless remote(s) not
reporting in to
ObserverIP Receiver.
The maximum line of sight communication range is about 300’. Move the
sensor assembly closer to the ObserverIP receiver.
Install a fresh set of batteries in the remote sensor(s).
Do not lay the sensor(s) flat.
Make sure the remote sensors are not transmitting through solid metal (acts
as an RF shield), or earth barrier (down a hill).
Radio Frequency (RF) Sensors cannot transmit through metal barriers
(example, aluminum siding) or multiple, thick walls.
Move the ObserverIP receiver around electrical noise generating devices,
such as computers, TVs and other wireless transmitters or receivers.
Temperature sensor
reads too high in the
day time.
Make certain that the sensor is not too close to heat generating sources or
strictures, such as buildings, pavement, walls or air conditioning units.
Make sure the thermo-hygrometer is mounted in a shaded area on the north
facing wall.
Use the calibration feature to offset installation issues related to radiant heat
sources. Reference Section 3.9.6.
Relative pressure does
not agree with official
reporting station
Make sure you properly calibrate the relative pressure to an official local
weather station. Reference Section 3.9.6 for details.
Data not reporting to
Wunderground.com®
1. Confirm your password 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.
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 your time zone is set properly. If incorrect, you may be
reporting old data, not real time data.
4. Check your router firewall settings. The ObserverIP sends data
via Port 80.
