The main aim of the project is to design a Intelligent helmet for coal miners. The system is a cost effective IOT based coal mine supervising system. This project is a realized real-time surveillance with early-warning intelligence on temperature, Humidity; leakage of gas in mining area, and alerting the control station by sending the values of the sensors in the Webpage. The system is used to reduce potential safety problems in coal production. Wi-Fi (Short for Wireless Fidelity) is a wireless technology that use radio frequency to transmit data through the air. Wi-Fi has initial speeds of 1mbps to 2mbps. Wi-Fi transmits data in the frequency band of 2.4 GHz. It implements the concept of frequency division multiplexing technology. Range of Wi-Fi technology is 40-300 feet. This system has gas sensor, temperature sensor, Humidity sensor interfaced to the microcontroller and the sensors information is transmitted to the control station using the Wi-Fi module. The system gives both audible and visual alerts using LCD and buzzer. The system also monitors the LPG gas leakages using gas detection sensor, fire and humidity using temperature and humidity sensor in the mines and if it exceeds the threshold level, it alerts through alarm using buzzer and also displays on LCD to the user. This sensors output is given to the Microcontroller, and we can see the values in the webpage by Wi-Fi Module.
