Organic vapor sensor - WSP2110

1. WSP2110 semiconductor organic vapor sensor product description

The WSP2110 semiconductor organic vapor sensitive element adopts advanced planar production process, forming a heater and metal oxide semiconductor gas-sensitive material on a miniature Al2O3 ceramic substrate, with electrode leads, packaged in a metal base and cap. When the detected gas is present, the higher the concentration of VOC gas in the air, the higher the conductivity of the sensor. A simple circuit can convert this change in conductivity into an output signal corresponding to the gas concentration.
