The MQ-4 Methane Natural Gas (CNG) Sensor Module is a highly sensitive and reliable sensor module used to detect methane and natural gas in the air. This module is designed for easy integration with microcontroller platforms, making it suitable for applications requiring gas detection, such as in gas leak detectors, air quality monitoring, and safety systems.

Key Features

High Sensitivity: The MQ-4 sensor is particularly sensitive to methane (CH4) and natural gas (CNG), making it ideal for environments where methane gas monitoring is critical.
Analog and Digital Output: The module provides both an analog voltage output that varies based on the gas concentration and a digital output that triggers when gas levels exceed a predefined threshold.
Fast Response Time: Quick detection of gas presence ensures timely alerts in safety-critical applications.
Adjustable Sensitivity: An onboard potentiometer allows users to adjust the sensor’s sensitivity for different application needs.
Wide Detection Range: Detects methane levels from approximately 200 to 10,000 ppm.

Working Principle

The MQ-4 sensor module operates based on a gas-sensitive semiconductor layer, which changes resistance in the presence of methane gas. The sensor’s resistance decreases with increasing gas concentration, allowing the module to measure gas levels through its analog and digital outputs.

Technical Specifications:

Operating Voltage: 5V DC
Detection Range: 200 – 10,000 ppm
Power Consumption: Less than 900mW
Output: Analog and Digital
Heater Voltage: 5V ± 0.1V
Preheat Time: ~20 seconds

The instruction of Wiring:-

VCC: positive power supply (5V)
GND: power supply is negative
DO: TTL switching signal output
AO: analog signal output

Applications

Gas leak detectors
Portable gas detectors
Air quality monitoring systems
Industrial safety equipment
Smart home safety devices

Package Includes:

1 Piece-MQ4-Methane Natural Gas Sensor (CNG) Module

Shipping
