MQ2 Gas Sensor Module Methane Butane LPG Smoke Gas Sensing
৳145
The MQ2 Gas Sensor Module is a versatile and reliable sensor designed for detecting gases such as methane, butane, LPG, and smoke. Widely used in gas leak detection systems, this sensor is perfect for ensuring safety in both residential and industrial settings. Its high sensitivity allows for early detection of dangerous gases, providing real-time alerts to prevent accidents. The MQ2 sensor is ideal for integrating into safety systems, environmental monitoring, and DIY projects in Bangladesh. With its easy-to-use interface and reliable gas sensing capabilities, the MQ2 Gas Sensor Module is a must-have for anyone looking to create a safer, more secure environment.
The MQ-2 Gas Sensor is highly sensitive to smoke and a variety of flammable gases, including LPG, propane, methane, and hydrogen. It is ideal for gas leakage detection systems in homes and industrial applications.
- LPG
- Butane
- Propane
- Methane
- Alcohol
- Hydrogen
The resistance of the sensor is different depending on the type of the gas.The smoke sensor has a built-in potentiometer that allows you to adjust the sensor digital output (D0) threshold. This threshold sets the value above which the digital pin will output a LOW signal.
