MQ-8 Gas Sensor: Hydrogen Gas
The MQ-8 Gas sensor 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.
