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 100-1000ppm.
This module provides both digital and analog outputs. Threshold level for digital output can be easily adjusted using the preset on the board. MQ-8 sensor module can be easily interfaced with Microcontrollers, arduino and etc.
