Coal Mine Safety System Using Wireless Sensor Networks and RFID Technology

Abstract

This paper designs a monitoring system for mine safety based on Radio Frequency Identification (RFID) wireless sensor network. In this project, there are two sections. The first section is underground section another section is ground section. In the underground section the sensor will sense the environment conditions such as temperature, humidity, gas, noise, tilt and this information is sent to the micro controller.  Micro controller sends the information through RFID transmitter. In ground section RFID receiver takes that information and sends to the controller and the controller sends the information to Global System for Mobile communication (GSM) modem as well as displays on the LCD. Here GSM modem sends the message to mobile whenever the sensor senses the data above threshold level. Also, a buzzer rings whenever there is danger.
