Gas sensor - MQ2

The MQ2 gas sensor is a highly sensitive component used for detecting various flammable gases and smoke in the air. This sensor is commonly used in household devices, such as gas leakage detectors, smoke alarms, and fire prevention systems. Its compact size and low power consumption make it suitable for integration into different electronic devices. The MQ2 sensor operates by measuring changes in the resistance of its sensitive component when exposed to different gases. It can detect gases like methane, propane, butane, alcohol, and smoke. The output of the sensor is an analog voltage that can be easily processed by a microcontroller or other digital devices. With its reliability and versatility, the MQ2 gas sensor is an essential tool for ensuring safety in various environments.
