  • Principle Introduction
Principle Introduction:
Winsen Electronics, research and produce air quality monitoring gas sensor for home and office air cleaners, and fresh air system.
WSP2110 VOC gas sensoradopts multilayer thick film manufacturing technology. The heater and metal oxide semiconductor material on the ceramic substrate of subminiature Al2O3 are fetched out by electrode down-lead, encapsulated in metal socket and cap. Conductivity of the sensor is affected by the concentration of target gas.The higher the concentration is, the higher conductivity of sensor gets. Users can adopt simple circuit to convert variation of conductivity into output signal corresponding to gas concentration.
Applications :
It is used in automatic exhaust device,air cleaner in domestic occasion for harmful gas detection.
Technical parameters :

Tips:For more parameter information, please refer to the latest manual provided by salesman.
