Transmitter Operation
|
The wireless transmitter reads data from a RH sensor and then sends the measured data over the air to a remote location. The measured relative humidity signals are converted to digital packets and then transmitted via a license free radio transmission to a waiting control receiver.
|
|
Receiever Operation
|
The wireless receiver decodes any incoming radio packets and converts them into linear voltage or current output signals for interfacing with PLCs, Controllers, Data Loggers or Process Measurement Instruments. |
