Project Description:

The main aim of this project is to design an IoT-based safety system that monitors coal mine conditions like temperature, water level, and dangerous gases. It helps in preventing accidents by sending real-time alerts to authorities and workers.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.
