·coal mines and transmit the data to the base station using Zigbee To monitor the concentration level of harmful gases present in coal mine like SO2 NO2 CO etc the semiconductor gas sensor are used We are also considering the health condition of person using fall detector accelerometer The removal of miner helmet is also a
·A safety monitoring helmet is being developed for the miners to help and rescue them at times of emergencies We have used an integrated sensor module which has various sensors such as gas sensors
·The aim of the project is to design a wireless helmet for coal miners using Zigbee wireless technology The system Is a value powerful ZigBee primarily based wireless mine supervising system
·This study attempted to investigate and design a new mechanism in monitoring safety by detecting gas concentration levels to prevent an explosion during welding activities at a high risk site
·project is coal mine supervising system which is based on the cost effective Zigbee technology Keywords—Smart helmet ZigBee Technology Gas sensor Humidity sensor temperature sensor coal miner s safety I INTRODUCTION As India is the third largest nation to produce coal in the world there will be many people working in Coal mines
·Using this layout the information gathered from the miner s helmets could be stored on a web server and shown in various ways all over the world The smart helmet and communication protocol that connects body and environmental sensors to an IoT setup made possible by LoRa are discussed in this study
·stumbling/slipping/falling or errors from malfunctioning or improperly used mining equipment In coal mine use of personal protective equipment like helmet shoes etc are not proper and proper arrangements were not there to check if the person is wearing personal protective equipment or proper
·The main objective of the project is to design a wireless helmet for coal miners using ZigBee wireless technology An intelligent helmet is used as a system with sensor network The system adapted a ZigBee module to keep an early check on various The people must wear the helmet while working in the coal mines Keeping all these aspects in
·A coal mine safety monitoring and alerting system using IoT can help improve safety in coal mines by providing realtime monitoring and alerting of hazardous conditions
