Winsen Electronics, research and produce air quality monitoring gas sensor for home and office air cleaners, and fresh air system.

WSP2110 VOC gas sensor adopts multilayer thick film manufacturing technology. The heater and metal oxide semiconductor material on the ceramic substrate of subminiature Al2O3 is fetched out by an electrode down-lead, encapsulated in a metal socket and cap. The conductivity of the sensor is affected by the concentration of the target gas. The higher the concentration is, the higher conductivity of the sensor gets. Users can adopt a simple circuit to convert the variation of conductivity into an output signal corresponding to the gas concentration.

It is used in automatic exhaust devices, and air cleaners on domestic occasions for harmful gas detection.


High sensitivity to toluene, benzene, formaldehyde, and other organic gases
Small component size
5V constant voltage, low power consumption
Fast response and recovery characteristics
Simple drive circuit
Excellent stability and long service life
