| 摘 要： | 基于低功耗nRF24L01无线收发器和MSP430F449单片机,采用短时突发式无线发射技术和低功耗休眠机制,设计一种超低功耗的传感器节点。测量结果表明,在电源电压为3.3V、平均数据率为1kb/s、发送功率为OdBmW、传输距离为10m、误帧率为0.12%时,本系统平均功耗约42μW,可以应用于光照、振动、热和气流等环境能量供电的无线传感器网络。

| Abstract: | Based on low-power wireless transceiver chip nRF24L01 and low-power microcontroller MSP430F449,an ultra- low-power sensor node was designed using bursty transmission technology and low-power sleep mechanism.Measurement results show that the system power consumption is about 421μW under 3.3V power supply,1kb/s average data rate and 0dBmW transmis- sion power.The frame error ratio is 0.12% when the transmission distance is 10 meters indoors.This system can be used in wire- less sensor networks powered by ambient light,vibrations,heat or airflow. |
