Project Description:

This system consists of a master controller and multiple slave controllers. The slave controllers are installed inside the coal mine and are connected to different sensors like temperature, water level, methane, and carbon dioxide. These slave units use RF modules to send data wirelessly to the master controller located at the control room. If any sensor detects abnormal levels, the master controller raises a local alarm and also sends the information to an IoT platform through Wi-Fi. This allows remote monitoring and quick action.The IoT-based coal mine safety monitoring system is a smart solution to reduce accidents and improve the working environment in coal mines. It ensures real-time monitoring and timely alerts that can help save lives. With further advancements, it can be made even more reliable, efficient, and user-friendly.Coal mines are highly hazardous environments where workers are exposed to toxic gases, poor visibility, high temperature, and the risk of accidents such as explosions or cave-ins. To enhance miner safety, an IoT-Based Coal Mine Safety Monitoring and Alerting System is developed to continuously track critical environmental parameters inside the mine and provide real-time alerts to both miners and the control room.This system uses a network of smart sensors, wireless communication modules, and IoT technology to monitor mine conditions. It immediately detects dangerous situations and ensures prompt warnings, helping prevent accidents and improving the overall safety infrastructure.
