Hydrogen Gas Sensor - MQ-8

This is a simple-to-use hydrogen gas sensor, suitable for sensing hydrogen concentrations in the air.
The MQ-8 can detect hydrogen gas concentrations anywhere from 100-10000ppm.

This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance.
The drive circuit is very simple; all you need to do is power the
heater coil with 5V, add a load resistance, and connect the output to an ADC.

This sensor comes in a package similar to our MQ-3 alcohol sensor,
and can be used with the breakout board below.
