Description

The MQ-6 Gas Sensor Module is a highly sensitive gas detection module designed for identifying Liquefied Petroleum Gas (LPG), butane, propane, and isobutane concentrations in the air. Using a reliable SnO₂ semiconductor sensing element, this sensor provides a quick and accurate response to gas leaks, making it ideal for home safety systems, gas leakage detectors, and industrial monitoring projects.

It outputs both analog and digital signals, allowing it to be easily interfaced with Arduino, ESP32, Raspberry Pi, and other microcontrollers.
