JIN Ren-cheng~1, WANG Yan-hui~2, WANG Li-ding~1, et al. Hardware implementation of wireless sensor networks node[J]. 2006, (12): 48-50+56. DOI: 10.13873/j.1000-97872006.12.016.
A novel solution of wireless sensor networks(WSNs) node is describel based on advanced RISC machines(ARM)core processor AT91SAM7S64
RF chip CC2420
temperature sensor MAX6666 and acceleration sensor ADXL202.After the analysis of system operation principle
the hardware design of WSNs node and the driver of on-board peripherals such as CC2420
MAX6666 and ADXL202 are expounded in detail.Finally
the performance of WSNs node especially temperature sensor is assessed by experiment.The wireless temperature sensor networks’accuracy is up to 0.25 ℃.
