IoT based smart helmet used in Mining Industry

This project presents the design and development of a smart helmet equipped with gas, temperature, and humidity sensors, along with a microcontroller unit and a 16×2 display. The helmet is designed to be worn by miners and workers in other industrial settings to provide real-time data on their immediate environment. The helmet’s microcontroller unit, based on the NodeMCU, collects data from the sensors and displays it on the helmet’s display, allowing the user to monitor the conditions around them. In addition to local monitoring, the helmet’s data can be transmitted to a web or mobile application, providing remote monitoring and alerting features. The application can generate alert signals on a buzzer in response to high concentrations of harmful gases, ensuring that the user is aware of potential hazards in their surroundings. The results of the project demonstrate the feasibility of a low-cost, wearable device that can improve safety and awareness for workers in hazardous environments. The smart helmet is versatile, and its design can be adapted to different industrial applications. This project lays the foundation for future research and development in the field of wearable technology for occupational safety..
