Product Description

Details

Sensitive material of MQ-136 gas sensor is SnO2, which with lower conductivity in clean air. When the hydrogen sulphide gas exists, the sensor’s conductivity gets higher along with the gas concentration rising. The conversion of the output signal, according to the gas concentration detected, is entrusted to a simple circuit, in order to be so easily interfaced to microcontroller or discrete in development kit such as Raspberry and Arduino.
