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 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.
4. 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.
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.
4.3 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.
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 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 100 m line of sight (no
interference, barriers or walls) but typically you will get 30 m 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.
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.
