COAL MINE MONITOR USING IOT AND WSN TECHNOLOGY
Coal mining is one of the most hazardous industries, where workers are constantly exposed to life-threatening risks such as toxic gas leakage, fire, flooding, rock falls, and lack of ventilation. Traditional monitoring systems in mines are often manual, delayed, and incapable of providing real-time data, which results in accidents and casualties. To address these challenges, this project proposes an IoT and Wireless Sensor Network (WSN) based coal mine monitoring system that ensures continuous, real-time, and remote surveillance of underground conditions.The system integrates multiple sensors including gas sensors (for methane, carbon monoxide, and carbon dioxide), temperature sensors, humidity sensors, and pressure sensors, which are deployed in the mining environment and connected through a WSN framework. The sensor data is transmitted wirelessly to a central gateway, which forwards it to the IoT cloud platform. Using cloud connectivity, the collected data is visualized and analyzed in real time on a web dashboard or mobile application, enabling remote monitoring by authorities. Additionally, the system triggers automatic alerts and notifications via SMS, email, or app notifications in case of abnormal parameters such as high methane concentration, low oxygen level, or sudden temperature rise, thereby reducing response time and enhancing worker safety.This IoT-WSN based coal mine monitoring system ensures scalability, energy efficiency, and low-cost deployment while providing a predictive safety mechanism that improves decision-making and prevents disasters. By combining the capabilities of IoT and WSN technologies, the system creates a reliable and intelligent safety framework for modern coal mining operations
