Key Highlights - The MQ-4 gas sensor is a device used to detect the presence of methane gas in the air. - It works by measuring the conductivity of the air, which changes when the sensor is exposed to methane gas. - The MQ-4 sensor is a type of metal oxide semiconductor (MOS) gas sensor. - It has a high sensitivity to methane gas and a fast response time, making it well-suited for detecting low levels of the gas. - The MQ-4 sensor outputs an analog voltage signal that can be read by a microcontroller or other control device. - It can operate at temperatures between -10 and 50°C, making it suitable for use in a wide range of environments. - The MQ-4 gas sensor is widely used in applications such as natural gas leak detection, indoor air quality monitoring, and in the oil and gas industry. Product Description MQ-4 Natural Gas sensor The MQ-4 gas sensor is a device that is used to detect the presence of methane gas in the air. It is often used in applications such as natural gas leak detection, indoor air quality monitoring, and the oil and gas industry. The MQ-4 sensor is a type of metal oxide semiconductor (MOS) gas sensor. It works by measuring the conductivity of the air, which changes when the sensor is exposed to methane gas. The sensor has a high sensitivity to methane, making it well-suited for detecting low levels of gas.
