The MQ-4 Natural Gas Methane Gas Sensor Module is a reliable and sensitive device designed for detecting the presence of methane gas and natural gas. The sensor module utilizes tin oxide (SnO2) as its gas sensing material, which exhibits low electrical conductivity in clean air but increases in conductivity as the concentration of combustible gas, such as methane, propane, and butane, rises.
The module features a simple circuit that converts the changes in conductivity to a gas concentration output signal. It provides a high sensitivity to methane gas and natural gas, making it suitable for monitoring gas leaks or concentrations in various applications.
The detection range of the MQ-4 sensor module for methane gas is 300 to 10,000 parts per million (ppm). It offers a high-quality dual panel design with power and TTL signal output indicators for easy monitoring and integration into systems. The module provides a DO switch signal (TTL) and an AO analog signal output, with the analog output voltage being proportional to the gas concentration.
With its long service life, reliable stability, rapid response, and recovery characteristics, the MQ-4 sensor module is an excellent choice for gas detection applications. It operates on a DC5V input voltage and consumes approximately 150mA of power. The module requires a preheating time of 20 seconds to ensure stable and accurate measurements.
The package includes one MQ-4 Natural Gas Methane Gas Sensor Module, providing a convenient solution for detecting and monitoring methane gas and natural gas. It is important to follow the manufacturer's instructions and safety guidelines for proper installation and usage of the sensor module.
