IoT based Smart Helmet for Automated and Multi-parametric Monitoring of Underground Miners’ Health Hazards

Safety has always been a concern for underground miners or construction site workers in general. The recent growth of the Internet of Things (IoT) and its applications has paved the way to monitor and track the safety of workers in real-time. This paper reports the design and development of an IoT-based smart helmet for real-time monitoring of the health and safety of workers in underground mines. The smart helmet was comprised of an array of ambient and flexible body sensors, which were wirelessly connected to the cloud via the LoRaWAN protocol, thereby establishing communication with the control room. The effectiveness and performance of this smart helmet were tested and analyzed.
