Hydrogen Sensor Module (MQ8)

Introduction:

This is a simple to use hydrogen 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.

Detects Hydrogen(H2), poorly sensitive to LPG, alcohol, cooking steam, CO.
