CHR01-3035 Series Humidity Sensitive Resistor
The CHR01-3035 series is an industrial-grade impedance-type polymer humidity sensor (humidity sensitive resistor) designed for accurate humidity measurement. It utilizes a functional polymer film coated on a conductive electrode ceramic substrate. The sensor's impedance changes logarithmically with relative humidity, driven by the migration of conductive ions within the polymer film influenced by moisture. This sensor offers high precision, reliability, excellent water resistance, adaptability to wide humidity ranges, stability, low drift, and good consistency. It is suitable for applications in dehumidifiers, humidifiers, transmitters, modules, electronic temperature and humidity meters, refrigeration, drying, meteorology, and other scenarios requiring humidity measurement.
