WSP7110 Hydrogen Sulfide Gas Sensor
The WSP7110 type hydrogen sulfide sensor adopts advanced plane production technology to form heater and metal oxide semiconductor gas sensor material on a micro Al2O3 ceramic substrate, which is led out by electrode leads and packaged in metal tube base and tube cap. When the detected gas exists, 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.
Sensor Features
High sensitivity to hydrogen sulfide gas
Small size of components
5V constant voltage, low power consumption
Fast response recovery feature
simple drive circuit
Excellent stability and long service life
main application
The gas sensor can be widely used in household and environmental Freon detection gas devices, etc.
