MQ-4 Methane Gas Sensor Module – 300–10000 ppm

QAR 19.00/ unit

Description

The MQ-4 Methane Gas Sensor Module is a metal oxide semiconductor sensor designed for detecting methane and natural gas concentrations in air. It provides both analog and digital TTL outputs, enabling flexible integration with microcontrollers and alarm systems. Operating at 5V DC with a built-in heater element, it delivers stable and repeatable measurements after proper preheating. The module is suitable for gas leak detection systems, safety monitoring applications, and embedded control projects.
