MQ-136 Hydrogen Sulfide Gas Detection Sensor
The MQ136 gas sensor utilizes SnO2 as its sensitive material, exhibiting lower conductivity in clean air. However, when exposed to H2S gas, the sensor’s conductivity increases proportionally with rising gas concentrations. This change in conductivity can be converted into an output signal corresponding to the gas concentration through a simple circuit. Known for its high sensitivity to H2S gas, the MQ136 sensor is also capable of effectively monitoring organic vapors containing sulfur. It serves as a cost-effective sensor suitable for various applications requiring gas detection capabilities.
Application
It is widely used in civil H2S gas alarm, industrial H2S gas leakage alarm and portable H2S gas detector, detection of toxic gas, harmful or hazardous gas.
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.
