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.
It is suitable for hydrogen leakage monitoring devices in households or industries. Can not be interfered with by ethanol vapor, oil fumes, carbon monoxide, and other gases.

After the sensor is powered on, it needs to be warmed up for about 20S to stabilize the measured data. It is normal for the sensor to heat up, because there is a heating wire inside, it will not be normal if the hand is hot.
