MQ-136 Hydrogen Sulfide Gas Sensor Module

This is a simple-to-use Hydrogen Sulfide gas sensor module, suitable for sensing Hydrogen Sulfide concentrations in the air. The MQ-136 can detect hydrogen gas concentrations anywhere from 1-200ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance.

MQ136 gas sensor has high sensitivity to H2S, also could be used to detect other vapor which contains Sulfur. It has low sensitivity to normal combustible gases.
