MQ-5 Gas Sensor For Methane(CNG), Propane, and Natural Gas Detector Module

MQ-5 Gas Sensor

The MQ-5 gas sensor is a device that is used to detect the presence of various gases, including methane, propane, and natural gas. It operates by measuring the resistance of a metal oxide semiconductor (MOS) material to changes in the concentration of the target gas in the air. The MQ-5 sensor is sensitive to a wide range of gases, making it suitable for use in a variety of applications, such as detecting gas leaks in homes and buildings, monitoring indoor air quality, and detecting the presence of harmful gases in industrial settings. The sensor has a fast response time and high sensitivity, making it capable of detecting small concentrations of gases.

The MQ-5 gas sensor consists of a sensing element, and a heating element. The sensing element is made of a metal oxide material that is sensitive to the target gas. The heating element is used to maintain the temperature of the sensing element at a constant level, which is necessary for accurate gas detection.
