MQ-136 Hydrogen Sulfide Gas Detection Sensor
The MQ136 gas sensor uses SnO2 as its sensitive material, which shows lower conductivity in clean air. When exposed to H2S gas, the sensor’s conductivity increases in proportion to the concentration of the gas. This change in conductivity can easily be converted into an output signal that correlates to the gas concentration through a simple circuit. Renowned for its high sensitivity to H2S gas, the MQ136 is also effective in detecting organic vapors containing sulfur. This cost-effective sensor is ideal for a variety of applications where reliable gas detection is required.
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.
