WSP2110 VOC Gas Sensor
Profile
WSP2110 VOC gas sensoradopts multilayer thick film
manufacturing technology.The heater and metal oxide
semiconductor material on the ceramic substrate of
subminiature Al

O
3
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.
Features
High sensitivity to organic gases such as toluene,benzene,methanal;quick response and resume; low power
consumption,simple detection circuit,good stability and long life.
Main Application
It is used in automatic exhaust device,air cleaner in domestic occasion for harmful gas detection.
