Wireless Network Based Mines Safety System Using ARM9

The method of mine safety monitoring system is becoming very important for the safety of the human. The underground environment conditions (such as gas, temperature, humidity and other environmental indicators) will not be constant. This underground environment becomes hazardous and it is difficult for the humans to work in the underground. To make the safety of the worker, many safety systems are introduced. In early days, the safety system was only mechanical. The system is equipped with the hardware design of both the microcontroller and the ZigBee sensor node and system software design.
