MQ6 Gas Sensor

The MQ6 Gas Sensor Module is a highly reliable gas detection device designed to detect LPG (Liquefied Petroleum Gas), butane, isobutane, propane, and other combustible gases. It uses SnO₂ (tin dioxide) as the sensing material, which exhibits lower conductivity in clean air and higher conductivity when combustible gases are present. The MQ6 is widely used in gas leakage detection systems, home safety devices, industrial safety systems, and Arduino-based IoT applications. It features both analog and digital outputs, making it easy to integrate with microcontrollers such as Arduino, Raspberry Pi, ESP32, and others. With its adjustable sensitivity, long life, and fast response time, the MQ6 is a reliable and cost-effective solution for flammable gas detection.
