This helmet is Under the mines due to uncomfortable situation the equipped with methane and carbon monoxide gas installation cost as well as maintenance cost is high sensor. This sensor sense the gas and the data is for wired communication networks...Coal mines are divided into two parts. The first section is the underground section and the other section is ground section. The underground part is the main part of the coal mine. This section is use to collect data from the sensors like temperature sensor, humidity sensor and gas sensor. The three sensors will observe the change

A cost effective ZigBee based wireless mine supervising system with voice over ZigBee (VoZ) is presented here. Here we design a smart helmet, which enable the helmet as a mobile sensor node of ZigBee wireless sensor networks, gathering parameters the temperature, humidity and illumination level of underground environment and will alert the central management unit in …...In coal mining areas carbon monoxide, methane, LPG gases are existing and they are very detrimental for human body. The purpose of mining safety helmet is to protect minors head against heavy object fall. The proper supervision and proper communication is an important requirement of mine industry. The smart helmet provides a real time

During mining operation dangerous gases. Like methane may be released into the air also underground mining hazards. Include suffocation, gas poisoning, roof collapse and gas explosion by keeping all those activity which done in underground coal mine we designed a system i.e. Zig bee based intelligent helmet for coal miners [7]...—Mining is a risky activity, the risk factor Abstract increases exponentially when it comes to underground mine. Working conditions in underground coal mines are much more dangerous than in underground metal mines, as it incorporates the risk of roof fall due to soft strata and the hazardous gases

Include suffocation, gas poisoning, roof collapse and gas explosion by keeping all those activity which done in underground coal mine we designed a system i.e. Zig bee based intelligent helmet for ...The improved safety features in our system dramatically increased anticipation of the coal miners by alerting them about the hazards. In our system, the helmet has the circuit with four sensors i.e. Temperature, humidity, gas, and oxygen level to watch the conditions in the coal pit.

IoT Based coal mine safety monitoring and controlling Maheswaran U Assistant Professor ... through a Zigbee wireless module attached to the helmet. When the concentration of methane or carbon monoxide gas ... It benefits from a clear circuit layout and low costs. However, because of the master-slave system...work in the mine. 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 parameters like methane, carbon monoxide, temperature and humidity inside the mine.

This paper presents implementation of safety helmet for coal mine workers. This helmet is equipped with methane and carbon monoxide gas sensor.
