MQ8 Gas Sensor Module
Product Details
The MQ8 Gas Sensor Module is a sensitive gas detection sensor specifically designed for detecting Hydrogen (H₂) gas. It is widely used in industrial safety systems, hydrogen leak detection, and environmental monitoring applications.
The sensor works using a semiconductor gas sensing element whose resistance changes when exposed to hydrogen gas. This change in resistance is converted into analog and digital output signals, making it easy to interface with microcontrollers such as Arduino, Raspberry Pi, ESP8266, and ESP32.
The MQ8 module usually includes an onboard comparator circuit and adjustable potentiometer, allowing users to adjust the gas detection sensitivity and threshold level. Its fast response, high sensitivity, and reliable performance make it suitable for both industrial safety systems and DIY electronics projects.
