MQ-2 SMOKE LPG BUTANE ...
The MQ-2 gas sensor module is a highly sensitive semiconductor sensor designed to detect various gases such as LPG (Liquefied Petroleum Gas), Butane, Propane, Methane, Alcohol, Hydrogen, and Smoke. It is widely used in gas leakage detection applications in homes, industries, and security systems. This module operates based on changes in resistance due to gas concentration. When the target gas is present, the sensor’s conductivity increases, allowing it to produce an output signal proportional to the gas concentration.
