MQ-5 GAS SENSOR

The MQ-5 Gas Sensor is a semiconductor gas sensor designed to detect LPG, natural gas, methane (CH₄), hydrogen (H₂), and other combustible gases in the surrounding environment. It operates by changing its electrical resistance when exposed to target gases, generating analog and digital output signals that can be easily interfaced with microcontrollers such as Arduino, ESP32, STM32, Raspberry Pi, and PIC. The sensor offers high sensitivity, fast response time, stable performance, and long operational life, making it suitable for continuous gas monitoring. Due to its reliability and low cost, the MQ-5 sensor is widely used in gas leakage detection systems, industrial safety monitoring, smart home gas alarm systems, environmental monitoring, and IoT-based gas sensing applications.
