Smart Helmet for Mining Industries

Through the integration of several sensors and communication modules, the smart helmet is intended to increase the efficiency and safety of mining activities. Accelerometers, temperature, humidity, and chemical detectors are among the sensors on the helmet that enable it to monitor its surroundings and quickly detect any hazards. The Internet of Things-enabled Smart Helmet gathers data from the sensors and wirelessly sends it to a central monitoring system for real-time analysis and visualisation. This enables prompt action to prevent accidents and ensure the safety of miners by identifying hazardous conditions early on. To optimise operations and resource allocation, the helmet can also provide relevant information about the productivity and working conditions in the mines. The foundation of this study is the ongoing monitoring of variables including temperature, humidity, and carbon monoxide in deep coal mines through the use of wireless transmission technologies for dialogue. The system that collects and stores data from the relevant sensors and makes decisions based on that data is a microcontroller-based one. Multiple alarm tones and an LED display system are used to notify the mine worker. People's health is negatively impacted by extreme weather. Therefore, it's critical to keep an eye on the employees' vital indicators at all times. The recommended system takes into account a number of environmental parameters including relative humidity ambient temperature and air quality. The communication technology is based on the IEEE 802.15.4 standard for LoRa which is trustworthy. This allows data to be wirelessly transmitted between the computer at the remote monitoring site and the hardware circuit at the local site which are the mines.
