The MQ2 Flammable Gas and Smoke Sensor Module is a highly sensitive and reliable device designed for detecting a range of combustible gases and smoke in various environments. This module is widely used in safety applications, environmental monitoring, and IoT projects due to its affordability, ease of use, and versatility.
Key Features:
- Gas Detection Range: Capable of detecting LPG, methane, butane, propane, hydrogen, alcohol, and smoke, making it suitable for multiple applications.
- Dual Output Modes:
- Analog Output: Provides a proportional voltage output that varies according to the concentration of gases detected, useful for continuous monitoring.
- Digital Output: Adjustable threshold output that triggers a digital signal when gas concentration reaches a set level, allowing for threshold-based alerts.
- High Sensitivity: Detects gases at concentrations from approximately 300 ppm to 10,000 ppm, ensuring responsiveness in real-time applications.
- Power Requirements: Operates on a standard 5V DC, compatible with most microcontroller platforms like Arduino, Raspberry Pi, and other development boards.
- Long Service Life and Stable Output: Designed for long-term use, with minimal maintenance and stable output characteristics over time.
Working Principle:
The MQ2 sensor employs a heating element and a metal-oxide semiconductor (MOS) material to detect gas. When the sensor is exposed to gases, the material’s resistance changes, which results in a varying output voltage. This allows for real-time monitoring of gas concentration levels.
Technical Specifications:
- Operating Voltage: 5V DC
- Sensitivity Range: 300 ppm to 10,000 ppm
- Operating Temperature: -20°C to 50°C
- Output Type: Analog voltage output (A0), Digital output with adjustable threshold (D0)
- Dimensions: Compact and easily mountable on a PCB
Applications:
- Home and Industrial Gas Leak Detection: Detects leaks of common household and industrial gases like LPG and methane, enhancing safety.
- Smoke Detection in Fire Alarm Systems: Alerts users in case of smoke presence, making it ideal for fire safety applications.
- Air Quality Monitoring: Measures ambient air quality for IoT devices and environmental monitoring systems.
- Automotive and Factory Safety Systems: Monitors gas levels in confined environments to prevent hazardous incidents.
Easy Integration:
The MQ2 module can be easily connected to microcontrollers and other electronics systems via its analog and digital outputs, making it a practical choice for DIY electronics enthusiasts and professionals. It provides reliable and accurate data, allowing for both threshold-based alerts and detailed gas concentration readings.
Example Applications in Projects:
- Kitchen Safety System: Use the MQ2 sensor to monitor LPG levels and alert in case of leaks.
- Fire and Smoke Detection System: Integrate into fire alarms to detect smoke and alert users quickly.
- Environmental Monitoring System: Create an IoT-based system to continuously monitor air quality and transmit data wirelessly.
Package Includes:
- 1Piece-MQ2-Flammable Gas and Smoke Sensor Module
