MQ136 Gas Sensor for Hydrogen Sulfide

Profile
Sensitive material of MQ136 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.
MQ136 gas sensor has high sensitivity to H2S gas, also can monitor organic vapour including sulfur well. It a kind of low-cost sensor for kinds of applications.

FEATUREs
   It has good sensitivity to H2S gas in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc.

Main Applications
   It is widely used in domestic H2S gas alarm, industrial H2S gas leakage alarm and portable H2S gas detector.
