Product Description
Product Overview
The CHR01-3035 series is an industrial-grade impedance-type polymer humidity sensor (wet-sensitive resistor) from CYBERSEN Sensing Technology. It utilizes a functional polymer film coated on a conductive electrode ceramic substrate, forming a sensitive component whose impedance changes logarithmically with relative humidity. This sensor is suitable for applications requiring humidity measurement, offering high precision, reliability, good water resistance, adaptability to wide humidity ranges, stability, low drift, and good consistency.
