The Methane Gas (CH4) Detection Sensor is a compact and reliable gas monitoring device designed for industrial safety, leak detection, and environmental monitoring applications. It supports Modbus RTU output for digital communication and also offers analog output options (0–10V or 4–20mA) for easy integration with PLC, BMS, EMS, and automation systems. Powered by 5V DC, the sensor provides stable performance, fast response, and high sensitivity for detecting methane gas in real time. It is suitable for gas detection systems, industrial plants, storage facilities, and closed environments where methane leakage monitoring is critical.
