MQ-6 LPG/Butane Gas Sensor Module

The MQ-6 gas sensor is a high-performance and highly sensitive gas detection module designed to identify LPG, butane gas, propane, and other combustible hydrocarbons in the air. It outputs an analog voltage that varies with the concentration of gas, allowing microcontrollers like Arduino, ESP32, or Raspberry Pi to measure gas levels accurately. With fast response, stable performance, and low maintenance, the MQ-6 is widely used in gas leak detection systems, home safety alarms, industrial monitoring setups, and portable gas detectors.

How the MQ-6 Sensor Works?

The MQ-6 uses a heated metal-oxide semiconductor that changes its resistance when exposed to combustible gases. This change in resistance is converted into an electrical signal that your controller can read. The analog output gives a variable voltage depending on gas concentration, while the digital output triggers when the gas level crosses a set threshold.
