MQ-2 Multi-Gas & Smoke Detection Sensor Module

The sensor measures the concentration of flammable gases in the air, the result can be obtained measuring the voltage on the analog output. The system is powered with the voltage of 5 V. The current consumption is about 150 mA. It has digital and analog output, making it compatible with most of the commissioning modules including Raspberry Pi and Arduino.

Features:

Wide Detection Range: Sensitive to gases such as LPG, methane, propane, hydrogen, alcohol, and smoke, with a detection range between 300 to 10,000 ppm.
Dual Output: Provides both analog and digital outputs, facilitating integration with various microcontrollers and systems.
Fast Response and High Sensitivity: Quickly reacts to the presence of target gases with high sensitivity, ensuring timely detection.
Simple Drive Circuit: Requires a straightforward circuit design, making it user-friendly for both beginners and experienced developers.

Specifications:

Power Supply: 5 V
Current consumption: 150 mA
Measuring range up to 10,000 ppm
Operating temperature: -20 to 50 °C
Analog and digital output
Resistor which pulls the sensor’s output to ground with a value of 1 kΩ
Pins: goldpin connectors, 2.54 mm pitch
Board sizes: 36 x 20 x 23 mm
It has mounting holes with diameter: 3.2 mm

Applications:

Domestic Gas Leakage Detector: Monitors household areas for gas leaks, enhancing safety.
Industrial Gas Detection: Ensures safety in industrial environments by detecting combustible gases.
Portable Gas Detectors: Used in handheld devices for field gas detection.

The digital output D0

With the help of placed on the reverse side of the board, potentiometer, set is the threshold, exceeding of which, causes the output D0 changing from a high to a low status. The pin D0 can be linked directly with a microcontroller or commissioning set, including Arduino, or for example, a module with a buzzer, which will signal a too low or too high level of unwanted gases in the air.

Analog output A0

The sensor has an analog output A0, which must be connected to the pin of the converter A/D (analog input in Arduino). This will allow you to measure the proportional voltage signal and more accurately determine the concentration.
