MQ136 Hydrogen Gas Sensor

Sensitive material of MQ136 gas sensor is SnO2, which with lower conductivity in clean air. When the target Hydrogen sulfide gas exist, the sensors conductivity is higher along with the Hydrogen sulfide concentration rising. Please use simple electric circuit, Convert change of conductivity to correspond output signal of gas concentration.
MQ136 gas sensor has high sensitivity to Hydrogen sulfide, Low sensitivity for other combustible gas. It is with low cost and suitable for different application.
Character:
1. Good sensitivity to Hydrogen sulfide
2. Simple drive circuit

Application:

1. Domestic Hydrogen sulfide detector
2. Industrial Hydrogen sulfide detector
3. Portable Hydrogen sulfide detecto
