About this product
The MQ-8 is a hydrogen gas sensor module with high sensitivity and fast response, suited to detecting hydrogen concentrations in air from 100 to 10000 ppm. It provides both analog and digital outputs and is used in gas leakage detection in homes, workshops and industrial equipment. Its sensitivity threshold can be adjusted with the onboard potentiometer.

How do I wire the MQ-8 module to an Arduino?
Connect VCC to 5 V and GND to ground, read the AO pin on an analog input for a level reading, and read the DO pin on a digital input for a threshold alarm. Turn the onboard potentiometer to set the digital trigger point.
Does the MQ-8 respond only to hydrogen?
No. It is highly sensitive to hydrogen, but it also responds in smaller amounts to alcohol, LPG and cooking fumes, so readings can be affected in a kitchen. The sensor also needs a warm-up period before its readings become stable.
