IOT Based Safety Helmet for Coal Minors

Abstract - Coal mine safety is a critical concern due to hazardous conditions like explosions, toxic gases, flooding, and collapses. Traditional monitoring and communication methods are inadequate, making modern solutions essential. The use of wireless networks, IoT devices, and sensor systems enables real-time monitoring of gas, temperature, humidity, and airflow. These technologies provide continuous data and instant alerts, ensuring faster response and improved miner safety. Keywords: Smart helmet, coal mining, IoT, safety, environmental monitoring.
