The RHU-222 & RHU-223 HUMENT type HPR-MQ humidity sensor are formed by depositing a humidity sensitive macro-molecule onto an electrode substrate. The resistance of the senor varies exponentially with variation relative Humidity.

The RHU series modules consist of an HPR-MQ sensor and an integrated circuit to provide a linear DC voltage output for 0-100% RH to enable easy user application of the HPR-MQ sensor. They are specifically designed for use in appliances and controllers.
