MQ136 Gas Sensor can be used to monitor the concentration Hydrogen Sulfide gas. This Module simplifies using the MQ-136 gas sensor by providing digital as well as analog output which can be interfaced to Microcontrollers, Arduino and Raspberry pi.

Senitive material of MQ136 gas sensor is SnO2, which with lower conductivity in clean air. When the target Hydrogen sulfide gas exist, the sensor’s 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.
