A Smart helmet can be detecting the hazardous events in the mines industry. In the development of helmet, we have considered the three main hazards such as air quality, helmet removal, and temperature. The first is the concentration level of hazardous gas like CO2. The first is The second hazardous event is when a miner removes the Helmet off his head. The third hazardous event is the rise in temperature. Presently, mining safety helmets only have the purpose of protecting the miner’s head against potential hazardous bumps. The safety helmets do not have any technology added to them to let miners know when a fellow miner has encountered a hazardous event. The literature on mines technology is available but very limited. For this helmet Co2, IR, and temperature sensors are used. The microcontroller which acts as a data processing unit used for getting all the data from the above sensors and concludes whether needs any intimation to the wireless unit or the user wearing it. Wireless transmission and alerting units are used to transfer the data obtained from the processing unit. It is achieved through Bluetooth and an android app.
