MQTT based Monitoring System for Coal Mine using Raspberry Pi

Abstract

Now a day’s due to global warming and climate changes there are challenging situations in coal mine. To reduce the cost as well as to improve the productivity along with product quality the automation in the field of coal mine is necessary, which will also reduce the mine workers efforts. This project proposes a design of a IOT system with MQTT protocol, by the help of Raspberry pi controller which is able to monitor the temperature, humidity, gas and status of smoke in an under ground mine. 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. Every sensor values gets reported through MQTT protocol at every certain interval of time. If there is any sudden increase in any of those sensor values along with data log, ten seconds of video has been captured and sends to the server’s mail.
