The Honeywell HCH-1000 Series Humidity Sensors are capacitive polymer sensors designed for relative humidity measurement. These sensors convert humidity value into capacitance, which can be measured electronically. Polyimide is used as a humidity sensing material because of its inherent IC (Integrated Circuit) processing compatibility, reduced temperature dependence and enhanced resistance against contamination. The HCH-1000 Series is manufactured using semiconductor technology. The sensor consists of a grid top electrode, a polyimide layer, and a bottom electrode. The grid top electrode on the bottom electrode provides enhanced sensitivity when compared to that of a standard structure. A cased version, for dust protection, and an uncased version are available.
