MQ-2 Smoke Gas Sensor

The MQ-2 Smoke, LPG, Butane, and Hydrogen Gas Sensor Detector Module is useful for gas leakage detection (home and industry). It is suitable for detecting H₂, LPG, CH₄, CO, alcohol, smoke, or propane. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by the potentiometer. The MQ2 gas sensor using gas-sensitive material is to be clean air in the lower conductivity of stannic oxide or tin oxide (SnO₂). The sensor works when flammable gases are present in the environment in which the conductivity of the sensor increases with an increasing concentration of combustible gas in the air. The MQ2 gas sensor module has higher sensitivity to liquefied petroleum gas, propane, hydrogen, detected gas, and other combustible vapors. This sensor can detect a variety of flammable gases and is a low-cost sensor for many applications. Package Includes: 1 x MQ2 Smoke Gas Sensor Module
