Coal Mining Safety using IoT

Now a day’s due to global warming and climate changes there are challenging situations in field of coal mine. To reduce the cost and improve the productivity along with product quality the atomization in the field of coal mine is indeed necessary, which will also reduce the mine workers efforts. This paper proposes a design of a wireless sensor network (WSN) with the help of Raspberry pi controller which is able to monitor the temperature, humidity, gas and status of smoke in an underground mine. This system also controls the ventilation demand to mine workers depending upon present climate conditions within the mine field. This system utilizes low power, cost effective Raspberry pi, a temperature sensor LM35, humidity sensor SYSH220, smoke detector, gas sensor for sensing the mine climate parameters and Wi-Fi for remote logging of data at central location to control the climate state with the help of motor and valve control circuitry. Traditional coal mine monitoring systems tend to be wired network systems, which play an important role in coal mine safe production.
