WSP5110 Planar Semiconductor Gas Sensor Is Used For Freon Detection Gas Devices In Home Environments

Features:

WSP5110 Freon gas sensor adopts advanced plane production technology, forming heater and metal oxide semiconductor gas sensitive material on micro Al2O3 ceramic substrate, led out by electrode lead, encapsulated in metal tube base and tube cap. When the detected gas is present, the higher the concentration of the gas in the air, the higher the conductivity of the gas sensor. This change in conductivity can be converted into an output signal corresponding to the gas concentration using a simple circuit.
