- • Detection Gas: Hydrogen Sulfide, H2S
- • Detection Range: 1～200ppm H2S
- • Application: It is widely used in domestic H2S gas alarm, industrial H2S gas leakage alarm and portable H2S gas detector.
- Principle Introduction:
Produce semiconductor hydrogen sulfide sensor, H2S Gas sensor MQ-136 for H2S gas alarm.
Sensitive material of MQ-136 gas sensor is SnO2, which with lower conductivity in clean air. When H2S gas exists, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.
MQ-136 gas sensor has high sensitivity to H2S gas, also can monitor organic vapor including sulfur well. It a kind of low-cost sensor for kinds of applications.
