وصف
QFM2100 Duct Sensor acquires the relative humidity in the air duct via its capacitive humidity sensing element whose electrical capacitance changes as a function of the relative humidity. This sensor acquires the temperature in the air duct via its sensing element whose electrical resistance changes as a function of the temperature.
