Smart Helmet for Coal Mine Workers

A more conventional version of the smart helmet has been developed to help miners while working in the mining sector. The mining industry frequently has dangerous occurrences, many of which end in fatalities or seriously injured parties. Using different sensors, the smart helmet able to recognize catastrophic situations such as presence of harmful gases like Carbon-Monoxide (CO), Methane (CH
4
), Ammonia (NH3) as well as temperature and humidity within the mine areas. Also the pulse of the coal miner monitored continuously so that it can be detected whether the miner is facing some difficulty or if any accident has occurred in the mine. Helmet wear by miner or not wear, is detected by an infrared sensor, hence negligence of the miner for not wearing the safety helmet can be avoided. Each sensor used has a threshold value that, if that value is exceeded, it causes the buzzer to activate, signaling the miners and supervisors. Wi-Fi and ThingSpeak is used for the remote transmission of information from coal mine to a central location. This technology may improve the safety and scale back accidents within the coal mines.
