This paper presents the design and implementation of a Microcontroller-based Coal Mine Safety Device integrated with advanced Embedded Systems. The primary objective of this innovative device is to mitigate the myriad of hazards and risks inherent in coal mining operations, thereby safeguarding the health and well-being of coal mine workers. Additionally, it prioritizes environmental considerations, ensuring a safe working environment conducive to optimal productivity. Through the strategic utilization of cutting-edge technology, this device offers comprehensive monitoring and response capabilities tailored to the dynamic conditions prevalent within coal mines. By addressing critical safety concerns and environmental factors, this development represents a significant advancement in promoting both occupational health and environmental sustainability within the coal mining industry. In the model, a range of sensors is incorporated to monitor temperature, humidity, and Air Quality Index (AQI) within coal mining environments. Through a meticulously devised plan and algorithm, the operation of both the microcontroller and the sensors is conducted autonomously, with their designated tasks being executed in alignment with the paper’s objectives. Auxiliary to this setup are strategically positioned slave nodes tasked with detecting pertinent environmental data, which is then transmitted to a central master node. This master node, when interfaced with a monitor, enables the remote monitoring of temperature, humidity levels, and Air Quality Index (AQI) without necessitating physical presence in the field.
