Real time monitoring of process parameters inside the underground or open cast mines in a reliable manner is a technical challenge for the mine industry. Real time monitoring can provide accurate information about different critical mining parameters like rise in humidity and temperature, presence of dangerous gases, presence of light etc. This monitoring can also pave way for the safety of the miners. Conventional wired communication has severe drawback regarding real time monitoring. This paper develops an ARM based embedded system which monitors the critical parameters inside the mine and transmits the data in wireless manner for better monitoring and visualization.
