Description
MQ2 gas sensor is a versatile detection device commonly used to detect a range of gases, including methane, propane, alcohol, carbon monoxide, and smoke. It operates by measuring the changes in electrical resistance of a sensitive layer inside the sensor when exposed to different gases. Often used in safety and environmental monitoring applications, the MQ2 sensor provides reliable gas detection for home safety systems, industrial settings, and air quality control. It is easy to interface with microcontrollers like Arduino for DIY projects.
