An MQ Sensor Module is a gas detection device used to sense the presence and concentration of various gases such as LPG, methane, smoke, alcohol, carbon monoxide, and ammonia. These modules use a sensitive gas sensor element that changes its resistance based on gas levels and provides analog and digital output signals. They are easy to interface with microcontrollers like Arduino, PIC, or Raspberry Pi and typically operate on low DC voltage. Most MQ modules include an onboard comparator and adjustable sensitivity using a preset potentiometer. MQ sensor modules are widely used in gas leakage alarms, air quality monitoring, safety systems, and automation projects.
