A Smart Helmet for Mining Industries

The disasters in underground coal mine are very serious issues now a days. A communication system must be there, between the workers of the mine, and the control station to improve the safety system in the mines. Therefore the purpose of the project is to modify an existing mining safety helmet to make the helmet even safer by adding a wireless sensor node network. A smart helmet has been developed that is able to detect the hazardous events in the mine industries. To improve miner safety, addition of intelligence to the mining helmet is needed. The miner needs to be warned when he removes his helmet. By using IR sensor we can detect it. Real-time monitor and control of mine hazard are more complex in the area of mining technology. Mine safety modules are configured to communicate to ground control or base station. A real serious issue in mines is hazardous gases. To detect the various gases present in the environment, gas sensor is used. Humidity sensor senses, measures and reports both moisture and air temperature. Temperature sensor measures the amount of heat energy or even coldness of environment. IoT module used here to update sensor data on web server. Buzzer will beep automatically if the sensor value exceed. Sensor related information will be displayed on LCD.
