Build your next gas-sensing prototype with the MQ-4 Methane Natural Gas Sensor Module. Designed to sense methane (CH4) and compressed natural gas (CNG) in the surrounding air, this module combines an MQ-4 sensor with analog and digital outputs for electronics experiments and microcontroller projects.
Monitor changes through the analog output, or use the adjustable digital threshold to trigger a response in your project. The onboard potentiometer lets you adjust the switching point, while the signal indicator LED provides a convenient visual reference during testing.
Key Features
- Methane and natural gas sensing: Suitable for methane/CNG detection experiments and gas-monitoring prototypes.
- Dual outputs: Analog output for monitoring sensor response and a TTL digital output for threshold-based switching.
- Adjustable threshold: Onboard potentiometer for setting the digital output trigger point.
- Active-low digital signal: The digital output switches low when the configured threshold is reached.
- Signal indicator: Onboard LED helps you observe the module's switching response.
- Convenient connection: Four-pin header with standard 2.54 mm spacing for integration into your circuit.
Specifications
- Sensor: MQ-4
- Target gas: Methane (CH4) / natural gas (CNG)
- Module supply voltage: 5V DC
- Outputs: Analog and TTL digital
- Analog output range: 0–5V
- Digital threshold adjustment: Onboard potentiometer
Project Ideas
Use this module to explore sensor readings, build threshold-triggered indicator circuits, or develop educational gas-monitoring demonstrations. It offers a practical way to compare a changing analog signal with a simple digital switching response.
Before You Connect
Check the module's pin labels and your controller's input-voltage limits before wiring. Do not connect a 5V output directly to an input that is not 5V tolerant. Follow the sensor manufacturer's warm-up and calibration guidance; an analog reading alone should not be treated as a calibrated gas concentration.
Important: Use this module for learning and prototyping, not as a substitute for a certified gas-leak alarm or a life-safety system.
