Smart Safety Helmet For Coal Miners

A cutting-edge smart helmet has been developed specifically for the coal mining sector to detect and address potential dangers faced by mine employees. The helmet’s design encompasses three primary risk categories: air quality, temperature, humidity, and accidents. Leveraging a Node MCU microcontroller board, equipped with gas, DHT, and GPS sensors, the helmet establishes connections to gather data effectively. This data is collected through a combination of digital and analog input/output pins, with analog readings converted to digital values. The processed data, including temperature, gas concentration, and GPS location, is then transmitted via Wi-Fi or cellular network to a remote server or cloud platform. The GPS functionality allows for real-time tracking of miners’ movements, while an emergency button enables prompt distress signaling to the control station. Gas sensor data undergoes comprehensive analysis to identify patterns or anomalies, informing decision-making processes aimed at enhancing safety, resource utilization, and operational efficiency in mining activities. Overall, the integration of the Node MCU board with gas, DHT, and GPS sensors facilitates real-time monitoring and analysis, promising significant improvements in production efficiency and worker safety within the mining industry.
