In this paper, the authors present a low power, cost-effective, and Zigbee protocol based wireless sensor network that provides an intelligent surveillance and safety system for underground coal mines. The system consists of wireless connection of several nodes. Sensor node mainly consists of Zigbee protocol based low power CC2530 transceiver integrated with a high performance, low power microcontroller on single chip. This integrated chip connected through RF connector on smartRF05 battery board. This small size, low power device is easily interfaced with desired miniature size sensors.
