Product Overview
The CHR03-3035 series is an impedance-type polymer humidity sensor (humidity-sensitive resistor). It features a functional polymer film coated on a ceramic substrate with conductive electrodes, forming a sensitive component whose impedance changes logarithmically with relative humidity. The conduction mechanism is influenced by the mobility of conductive ions within the polymer film due to the presence of water molecules. This sensor is designed for applications requiring humidity measurement, offering improved consistency, reduced hysteresis, faster recovery time after drying, and higher stability compared to previous generations.
