he MQ-2 Gas Sensor Detector Module has a detection range of 300 to 10,000 ppm and is known for its durable and simple design, making it effective at detecting toxic gases in very low concentrations.
This module is ideal for gas leak detection in both residential and industrial settings. It can detect gases such as H2, LPG, CH4, CO, alcohol, smoke, and propane. Thanks to its high sensitivity and fast response time, it provides quick measurements. The sensor's sensitivity can be adjusted using the onboard potentiometer.
The MQ-2 sensor utilizes a gas-sensitive material with low conductivity in clean air, such as stannic oxide (SnO2). When combustible gases are present, the sensor's conductivity increases in proportion to the concentration of the gas in the environment.
A simple circuit is used to convert the changes in conductivity into an output signal that corresponds to the gas concentration.
