MQ-8 Hydrogen gas detection sensor module

MQ-8 Hydrogen gas detection sensor module

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 high sensitivity and a 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.

Advantages:-

1. High sensitivity to Natural gas
2. Long life and low cost
3. Simple drive circuit
4. Domestic gas leakage
5. Industrial CO detector
6. Portable gas detector
