MQ-4 Methane & Natural Gas Sensor Module
Detect the presence of Methane (CH4) and Natural Gas with the high-sensitivity MQ-4 Gas Sensor Module. This sensor is specifically optimized for detecting Methane, the main component of natural gas and Compressed Natural Gas (CNG), making it an essential component for safety and environmental monitoring projects.
The MQ-4 offers excellent sensitivity and a fast response time, ideal for building reliable gas leak detectors. This easy-to-use breakout board includes all the necessary electronics, featuring a dual-output system for maximum versatility. The **Analog Output (A0)** provides a real-time voltage reading proportional to the Methane concentration, while the **Digital Output (D0)** acts as a simple alarm, triggering when the concentration surpasses a user-defined threshold.
This trigger point can be precisely calibrated using the onboard potentiometer, allowing you to customize the sensor’s sensitivity for your specific application. For any project requiring dependable Methane detection, the MQ-4 is a top choice.
Key Features:
- Sensor Model: MQ-4
- Primary Detection: High sensitivity to Methane (CH4), Natural Gas, CNG
- Dual Output: Provides both Analog (voltage) and Digital (HIGH/LOW) signals
