Hydrogen gas detection sensor module

Subcategory
EMS - Input: Sensors

Description

The MQ-8 Hydrogen Gas Sensor is a semiconductor sensor used to detect hydrogen (H₂) gas in the range of 100 ppm to 10,000 ppm. It works using a SnO₂ sensing layer that changes resistance when exposed to hydrogen. It provides analog and digital outputs and is used in safety systems, gas monitoring, and Arduino/ESP32 projects.
