Product Description:
The MQ-2 Gas Sensor Module is a versatile gas detection device capable of sensing a wide range of gases including LPG, smoke, alcohol, propane, hydrogen, methane, and carbon monoxide. This low-cost sensor is ideal for various applications such as gas leakage detection, air quality monitoring, and fire prevention systems.
Key Features:
- Wide Detection Range: Detects combustible gases and smoke with a concentration range of 300 to 10,000 ppm.
- Dual Output: Provides both analog (AO) and digital (DO) outputs for versatile applications.
- High Sensitivity: Sensitive to various gases including LPG, propane, hydrogen, methane, and smoke.
- Fast Response Time: Quickly responds to changes in gas concentration.
- Adjustable Sensitivity: Sensitivity can be adjusted using an onboard potentiometer.
Specifications:
| Parameter | Value |
|---|---|
| Supply Voltage | DC 5V |
| Power Consumption | 150mA |
| A0 Output Voltage | 0.1V – 4V (depending on gas concentration) |
| DO Output | TLL digital output (0 and 1) |
| Sensitivity Range | 300 – 10,000 ppm (flammable gases) |
Applications:
- Gas Leak Detection: Ideal for monitoring gas leaks in homes and industries.
- Smoke Detection: Useful in fire detection systems to monitor smoke levels.
- Air Quality Monitoring: Helps in assessing indoor air quality by detecting harmful gases.
- Portable Gas Detectors: Can be used in handheld devices for gas detection.
Wiring Connections:
- VCC: Connect to positive power supply (5V)
- GND: Connect to ground
- A0: Analog output voltage correlating with gas concentration
- D0: Digital output signal indicating gas detection
