Abstract: By analyzing low power consumption mode of CC2530 and sleep or wake-up mechanism of Z-Stack protocol stack based on ZigBee protocol, a terminal node of mine wireless sensor network was designed which was based on CC2530. Energy consumption of the terminal node was tested through a measurement method based on Fluke multimeter. Conclusions are as following. Current consumption is the maximum when the terminal node establishes a connection with a coordinator, but smaller in sleep or wake-up mode. Average operating current of the terminal node is less affected by transmitting power. Sleep cycle of the terminal node directly affects current consumption, and the longer the sleep cycle, the lower the energy consumption.
