Description:
The MQ-4 Methane Gas Sensor Module is designed for detecting methane (CH₄) and natural gas (CNG) concentrations in the air. Compatible with Arduino and other microcontrollers, this module is ideal for gas leak detection, home safety systems, and environmental monitoring projects.


Specification:
- Detection of gas: Natural gas/Methane
- Detection of Concentration:300-10000ppm
- Input voltage: DC5V
- Power consumption (current): 150mA
- DO output: TTL digital quantities 0 and 1 (0.1 and 5V)
- AO output: 0.1-0.3V (relatively non-polluting), the highest concentration voltage is about 4V
- Using the chip: AT89S52
- Crystal: 11.0592MHZ
- Baud rate: 9600
- Compilation environment: Keil
Features:
- Gas Detection: Sensitive to methane and natural gas; less sensitive to alcohol and smoke.
- Output Types: Provides both analog (0.1–5V) and digital (TTL) outputs for versatile integration.
- Preheating Time: Requires a minimum of 24 hours of preheating for optimal accuracy.
- Operating Conditions: Functions within a temperature range of -10°C to 50°C and humidity levels of 65% ±5%.
- Power Requirements: Operates at 5V DC with a current consumption of approximately 150mA.
- Sensitivity Adjustment: Features a potentiometer to adjust sensitivity levels.
-
Long Lifespan: Offers stable performance over extended periods.
Applications:
- Gas Leak Detection: Monitor and detect methane or natural gas leaks in residential and industrial settings.
- Safety Systems: Integrate into home automation systems for real-time gas monitoring.
- Environmental Monitoring: Use in projects aimed at assessing air quality and pollution levels.
-
Educational Projects: Ideal for learning and experimentation with gas sensors and microcontroller interfacing.
