This MQ-8 gas sensor is specially designed to detect hydrogen and other hydrogen-containing gases. The material used in this sensor is SnO2. When there is hydrogen in the surrounding medium, the electrical conductivity of the sensor increases in proportion to the amount of gas. This change in electrical conductivity can be converted to the output signal corresponding to the gas concentration with just one circuit.


This sensor offers:

* good sensitivity to hydrogen over a wide range of concentrations;
* long duration at low cost;
* simple driver circuit.


May apply:

* in a domestic leak alarm;
* in an industrial-grade hydrogen alarm;
* on a portable gas detector.
