Best Practices For Wireless Communication; Observerip Receiver; Hardware Requirements - Ambient Weather WS-0800-IP ObserverBase User Manual

Note: Do not install the thermo-hygrometer-barometer transmitter outside. This will cause errors
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 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 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.
