The GQG5 Mining Smoke Sensor is designed for real-time smoke detection in underground coal mine environments, particularly for monitoring potential fire hazards in coal transportation systems, rubber/plastic conveyor belts, where combustion may occur.
The sensor detects smoke concentration changes and provides timely audible and visual alarms when abnormal conditions exceed preset thresholds, helping improve early fire detection capability and enhance underground mine safety management.
