About this product

The MQ2 Gas Sensor Module is designed to sense the presence of various gases in the surrounding air. It operates by changing its resistance based on gas concentration, providing an output signal that reflects the detected levels. This makes it suitable for monitoring gas presence in different environments.

Features

Sensitive to LPG, propane, and hydrogen
Output voltage increases as gas concentration increases
Fast response and recovery
Includes boost circuit
Adjustable sensitivity
Signal output indicator

Pin Configuration

For Module:
1. Vcc: Powers the module, typically +5V
2. Ground: Connect to system ground
3. Digital Out: Digital output (use the potentiometer to set threshold)
4. Analog Out: Outputs 0–5V analog voltage proportional to gas intensity
For Sensor:
1. H-pins: Of the two H pins, one connects to supply and the other to ground
2. A-pins: A and B pins are interchangeable; these are tied to supply voltage
3. B-pins: A and B pins are interchangeable; one acts as output while the other is pulled to ground
