摘要
设计了一种具有质量轻、体积小、低成本、低能耗的无线传感器网络节点。该节点由MSP430单片机、CC2420射频收发器、FT232BM转换芯片、SHT11温度湿度传感器、外围芯片、电源电路以及JTAG调试接口组成。通过JTAG调试,以及安装TinyOS操作系统,节点较好地实现了数据采集、无线传输以及无线网络功能。
A wireless sensor network node with The node uses the MSP430 microcontroller as MCU, light weight, small size, low energy consumption is designed. CC2420 as RF transceiver, FT232BM as conversion chip, and SHTll temperature and humidity sensor. The other peripheral chips, power circuit and JTAG debugging interface are also included. Through JTAG debugging and the installation of TinyOS operating system, the date collection, wireless transmission and networking function are achieved effectively.
