IOT BASED MINE HAZARD DETECTION AND SAFETY MONITORING APPARATUS

Abstract

Mining is the most hazardous activity, especially in underground mining lot of care must be taken
about the safety of workers because the environment may change drastically due to the poor air circulation.
Hundreds of miners are dying every year across the world and to overcome this problem, we have developed a
prototype model of smart helmet equipped with sensors for the safety of workers. In fact, often the temperature
and humidity will change drastically inside the mine and sometimes miners are dying due to the toxic gasses. So
we have focussed mainly over these three parameters and are monitored continuously using suitable sensors and
information will be transmitted to the concern mobile phone directly through Wi-Fi module interfaced with
main processor built with Arduino board. The sensors placed over the helmet can detect any hazardous changes
and alert the miners through buzzer. Means if the system detects any toxic gasses, immediately alarm will be
energized. Similarly if the temperature is more than the 29 C or humidity is more than the 60%, buzzer will be
activated and message will be sent to the concern care taker mobile phone. Here the system is designed to send
the parameters values continuously. ESP 8266 IOT device is used to establish a wireless communication link
between the phone and processing unit such that the message will be transmitted directly to the phone. LCD is
used to display the parameter values continuously and the same data will be transmitted. Since it is a prototype
module, the hardware used for the purpose may not accommodate over the helmet and hence it is assembled
over a tiny plank and sensors are arranged over a helmet. 12 v rechargeable battery is used to energize entire
system and it can be charged when required.
