MQ-2 Gas Sensor Module – Methane, Butane, LPG, Smoke

The MQ-2 Gas Sensor Module is a versatile sensor that can detect or measure various gases including LPG, Alcohol, Propane, Hydrogen, CO, and even methane. This module version of the sensor features a digital pin, allowing it to operate independently without a microcontroller. It is particularly useful when you need to detect a specific gas. For measuring gas levels in parts per million (ppm), the analog pin is utilized, which is TTL driven and compatible with most common microcontrollers.

Applications:

Gas detection and measurement: The MQ-2 Gas Sensor Module can accurately detect and measure gases such as LPG, Alcohol, Propane, Hydrogen, CO, and methane, making it suitable for applications in industrial environments, laboratories, and homes.
Air quality monitoring: Use the MQ-2 Gas Sensor Module to monitor air quality and detect harmful gases in indoor or outdoor environments. It helps maintain a safe and healthy living or working environment.
Gas leak alarm: Install the sensor module in areas prone to gas leaks, such as kitchens, gas storage facilities, or industrial settings, to receive timely warnings and prevent accidents.
Safety standard maintenance: The MQ-2 Gas Sensor Module aids in maintaining safety standards by providing reliable gas detection capabilities. It is widely used in industries where gas leakage is a concern, such as oil refineries, chemical plants, and manufacturing facilities.
Environmental standards in hospitals: Hospitals and healthcare facilities can benefit from using the MQ-2 Gas Sensor Module to ensure compliance with environmental standards. It helps monitor the air quality and detect any harmful gases present.

Features:
