Pre Installation and Site Survey
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 wi-
reless range of the weather station.
Site Survey
Perform a site survey before installing the weather station. Consider the following:
• You must clean the rain gauge once per year and change the batteries every two years.
Provide easy access to the weather station.
• 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.
• 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 buil-
ding is 6m tall, install 4 x 6m = 24m away. Use common sense. If the weather station is
installed next to a tall building, the wind and rain will not be accurate.
• Wireless Range. The radio communication between receiver and transmitter in an open
field can reach a distance of up to 100 m, providing there are no interfering obstacles
such as buildings, trees, vehicles, high voltage lines. Wireless signals will not penetrate
metal buildings. Most applications will only reach 30m due to building obstructions, walls
and interference.
• 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 moun-
ting locations.
Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls and metal barriers.
We recommend the following best practices for trouble free wireless communication.
• Electro-Magnetic Interference (EMI). Keep the console several feet away from computer
• monitors and TVs.
• Radio Frequency Interference (RFI). If you have other 433 MHz devices and communica-
tion is intermittent, try turning off these other devices for troubleshooting purposes. You
may need to relocate the transmitters or receivers to avoid intermittent communication.
