Mining helmets primarily protect against solid impacts, yet detecting hazardous gases is vital in deep mines. Improved security is imperative due to the severity of underground disasters such as gas explosions and inadequate lighting. Blame for accidents often rests on supervisors, emphasizing the need for better communication among miners, supervisors, and control stations. The proposed system aims to bolster mining safety by integrating a network into helmets. This network senses the miner’s environment and transmits real-time data online via IoT. This enables the control station to monitor conditions and provide immediate assistance during emergencies. The system comprises an Arduino microcontroller, LCD, and buzzer for signaling coworkers during crises. Various sensors, including those for Gas, Humidity, Temperature, LDR, and IR, contribute to the system’s functionality, with the IR sensor acting as a helmet removal sensor.
