Smart Helmet For Mining Workers Using Iot

Abstract

Mining is one of the most dangerous professions, with miners frequently exposed to harmful environmental conditions like poisonous gases, high temperatures, and low oxygen levels. In order to improve the safety of miners, this project suggests the creation of a smart helmet based on LoRa (Long Range) technology and the ESP32 microcontroller. The intelligent helmet is equipped with several sensors, such as gas sensors (for detecting toxic gases like carbon monoxide and methane), temperature sensors, and humidity sensors, as well as a GPS module for real-time tracking. The data collected from these sensors is processed on the ESP32 microcontroller and wirelessly transmitted over long distances via LoRa technology so as to provide continuous monitoring from a centralized control room. During critical situations, like the presence of toxic gases or hazardous temperature levels, the helmet produces audible and vibrational signals to alert the worker and, at the same time, sends an emergency signal to the monitoring system. This preventive measure minimizes the chances of accidents and facilitates timely intervention. The suggested system is energy- efficient, light in weight, and can work in harsh mining conditions. By taking advantage of LoRa's long-distance communication and ESP32's computing power, this intelligent helmet greatly enhances the safety and monitoring efficiency of workers in the mining field.
