MQ2 Smoke LPG Butane Hydrogen Gas Sensor

Description :

The MQ-2 sensor is a gas sensor module designed to detect various gases, including smoke, LPG (liquefied petroleum gas), butane, and hydrogen. It is widely used in gas leakage detection and air quality monitoring applications. Here are some key features and information about the MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module:

Key Features :

1. Gas Detection : The MQ-2 sensor is sensitive to a range of gases, including smoke, LPG, butane, and hydrogen.

2. Analog Output : The module typically provides an analog voltage output that varies based on the concentration of the detected gas. The higher the gas concentration, the higher the analog voltage.

3. Heating Element : Similar to other MQ series sensors, the MQ-2 sensor contains a heating element that is used to heat the sensing element, ensuring stable and accurate readings.

4. High Sensitivity : The MQ-2 is known for its high sensitivity to combustible gases and smoke.

5. Application Range : It is commonly used in applications such as gas leakage detection, smoke detection, and air quality monitoring.

6. Interfacing with Microcontrollers : The MQ-2 sensor can be easily interfaced with microcontrollers like Arduino for integration into electronic projects.

7. Calibration : Calibration may be required for accurate gas concentration readings. Refer to the sensor's datasheet for specific calibration instructions.

Pin Configuration :

The MQ-2 sensor typically has the following pin configuration:

• VCC: Power supply (5V)
• GND: Ground
• AOUT: Analog output (connects to an analog input pin on a microcontroller)
• DOUT: Digital output (some modules may have a digital output pin)
