MQ-2 Smoke & Flammable Gas Sensor Module
Add safety and environmental awareness to your projects with the MQ-2 Gas Sensor Module. This versatile and highly sensitive sensor is designed to detect the presence of flammable gases and smoke in the air, making it an excellent choice for building gas leak detectors, air quality monitors, and fire alarm systems.
The MQ-2 is primarily sensitive to LPG, Butane, Propane, Methane, Alcohol, Hydrogen, and smoke. This module makes the sensor easy to use by providing all the necessary supporting circuitry on a single board. It features a dual-output design: an **Analog Output (A0)** that provides a real-time voltage reading proportional to the gas concentration, and a **Digital Output (D0)** that goes HIGH when the concentration surpasses a user-defined threshold.
An onboard potentiometer allows you to easily adjust the sensitivity of the digital output, calibrating it for your specific application. With its fast response time and stable performance, the MQ-2 is an essential component for any safety-critical electronics project.
Key Features:
- Sensor Model: MQ-2
- Gases Detected: LPG, Butane, Propane, Methane, Alcohol, Hydrogen, Smoke
- Dual Output: Provides both Analog (voltage) and Digital (HIGH/LOW) signals
- Adjustable Sensitivity: Onboard potentiometer to set the digital output threshold
- Operating Voltage: 5V DC
- Interface: 4-pin header (VCC, GND, D0, A0) for easy connection
- Fast Response: Quick detection and recovery times
Applications:
The MQ-2 sensor is ideal for a wide range of applications, including domestic gas leak detectors, industrial combustible gas alarms, portable gas detectors, air quality monitoring systems, and fire/smoke detection projects for Arduino and other microcontrollers.
