In early days mining was a very arduous job where many accidents were often reported. The smart mine safety system is basically a wireless sensor network in mines which aims at providing a safer environment through complex wireless network to monitor all the parameters continuously. It enables the miners to work in a safe environment as it assures the real-time monitoring with the help of electronic sensors and transducers as well as wireless communication.

Underground mining is considered as one of the dangerous job as the environmental parameters (gas, temperatureand humidity) are not constant with time. These parameters may exceed a certain limit and become hazardous which for the humans to work there. The gaseous underground atmosphere is potentially hazardous as it can cause fire or explosion and asphyxiation or other health issues to the miner, which proves fatal to the miner most of the times. For monitoring of such time varying parameters, the current communication and monitoring systems are cable based and are discrete in nature. Cable based communication and monitoring systems have the following shortcomings:  Susceptible to failure of the entire monitoring system during any type of cable breakage at the time of disaster.  Possibility of sparks or flames between connections of cables.  Communication only from point to point is available. It cannot establish a connection from a random place in the mine. Hence, it is unable to communicate with the moveable miner.  With the working surface expanded, blind spotsfor monitoring appear, and thus, new installation and maintenance is needed. These cables are costly and the whole scalability of the system becomes non- economic. Therefore, development of cost-effective, reliable, maintenance-free, continuous monitoring and safety solution of underground mine workers’ is a burning need today. In this paper, we propose an efficient and smart alternative to the currently employed cabling mine monitoring system. Real time sensor data is displayed using a live plot and corresponding sensor values are wirelessly transmitted using a Wireless Personal Area Network (WPAN) in the current research work. A low cost and low power Data Acquisition System (DAS) is emulated for effective sampling and transmission of sensor data in a standardized format. II. THE ACTUAL SYSTEM. The developed system can be divided into two sections. First is a hardware circuit that will be mounted on the body of the mine workers. This may be preferably fitted with the safety kit which the miner wears around their waist. The circuit has a sensor module consisting of gas, temperature, humidity and pulse-rate sensors. Gas concentration is meant for the harmful gases like methane, ammonia and carbon-monoxide and is measured in units of ppm (parts per million).
