Description
Measurement of the relative humidity is based on the
principle of capacitive polymer sensor.
Measurement of relative humidity and temperature
are available on the receiver either via RS485 serial
interface with Modbus communication or via two
analog outputs.
The sensor efficiently controls ventilation systems,
based on current room air quality.
Low battery power is indicated by a built in LED
indicator.
