Abstract:
In this paper,we design and implement a low-power wireless sensor network node.Firstly,by analyzing and comparing a variety of exiting node design,we select low-power chips,and propose a low-power node design based on the MSP430F149 processor and nRF24L01+wireless transceiver chip.Then,we describe the system software design.Finally,we test and analyze the energy consumption of the node carefully.The results show that the proposed node design and energy management strategies can achieve low power consumption of the node.
