The MQ-2 Gas Sensor is a versatile, high-sensitivity sensor designed for detecting a variety of gases, including LPG, smoke, methane, carbon monoxide (CO), and alcohol. This sensor is ideal for use in air quality monitoring, fire detection, and home safety systems. With its ability to provide analog output based on the concentration of gases in the air, the MQ-2 sensor can be integrated into projects involving microcontrollers such as Arduino, ARM, or other MCU-based platforms.
It operates by heating a sensing material in the presence of specific gases, altering the resistance, which is then converted to a readable signal. The MQ-2 sensor features a fast response time and long-term stability, making it a popular choice for embedded applications. Easy to interface with through its analog output pin, this gas sensor ensures that you can easily build gas detection systems for a range of use cases.
