Smart Electronics Hydrogen sulfide sensor probe MQ-136 Toxic gas H2S sensor MQ136
The gas-sensitive material used in the MQ136 hydrogen sulfide gas sensor is tin dioxide (SnO2) with low conductivity in clean air. When there is hydrogen sulfide gas in the environment where the sensor is located,
the conductivity of the sensor increases as the concentration of hydrogen sulfide gas in the air increases.
Using a simple circuit, the change in conductivity can be converted into an output signal corresponding to the
gas concentration.
Features:

Sensor characteristics
The MQ136 hydrogen sulfide gas sensor has high sensitivity to hydrogen sulfide, and is ideal for monitoring
other sulfur-containing organic vapors, but has low sensitivity to common combustible gases. It is a low-cost
sensor suitable for many applications.
Main Application
Hydrogen sulfide gas alarm detector, leak alarm
