Smart safety helmet for coal mine workers in li-fi

Electronics and communication engineering

Mining is the first step in the dirty life cycle of coal. When coal mines move in, whole communities are forced off their land by expanding mines, coal fires, subsidence, and overused and contaminated water supplies. Mines are quick to dig up and destroy forests and soils. But once the coal is gone, the problems they leave behind, like acid mine drainage, can persist for decades. Around the world, Greenpeace campaigns to help communities stop coal mines, and speed up the shift to 100 percent clean, safe renewable energy. In this paper we are going to safe the coal mine workers by implementing the smart safety helmet. In this we are going to use Arduino (atmega328p), temperature sensor, humidity sensor, and heartbeat sensor and smoke sensor. The temperature at the workspace, humidity level in air, detection of any gasses, heartbeat level of the workers are the parameters to be considered during their work. These parameters are sensed by those respective sensors and the information is collected by the Arduino and they are monitored at the base station. The medium between the transmitter and receiver is light. The light is modulated in such a way that they can deliver the values from sensor at transmitter side and deliver them to the receiver end
