MQ-136 Hydrogen Gas Sensor


In stock

The MQ-136 is a Hydrogen Sulfide detection sensor with a sensing range of 1 - 200ppm. The sensing element is SnO2, which has lower conductivity in clean air. When H₂S gas exists, the sensor's conductivity gets higher along with the gas concentration rising.

  • Sensitive material of MQ136 gas sensor is SnO2, which with lower conductivity in clean air. When the target Hydrogen sulfide gas exists, the sensor’s conductivity is higher along with the Hydrogen sulfide concentration rising. Please use a simple electric circuit, Convert change of conductivity to correspond output signal of gas concentration.
  • MQ136 gas sensor has a high sensitivity to Hydrogen sulfide, Low sensitivity for other combustible gas. It is at a low cost and suitable for different applications. Character:
  • Good sensitivity to Hydrogen sulfide
  • Long life and low cost
  • Simple drive circuit
