Nowadays the safety of the coal miner is the biggest task or we can say the safety of the worker in the coal mine is a major problem. Many problems faced by the miners while mining such as lungs problem, hazards, while digging due to the noise of machine miner can't able to listen properly and there is no proper light system for them, high temperature, darkness, harmful gases, etc. As mines are deeper, there is more risk of collapse. A coal mine safety and alerting system is the solution to these challenges. The aim is to use IoT technology to make safety systems smarter. This system includes a microcontroller, gas sensor, vibration sensor, LDR sensor, crystal oscillator, WIFI module, buzzer, LCD, and relay LED indicators. The things that humans can't able to sense, this smart sensor will do, this is the reason we are using this.

Internet of things (IoT), Arduino UNO, Relay, Buzzer, sensor, Environment condition detector, gases detector system.
