摘要
为实现环境温度的实时监测,提出了无线温度传感器节点的软硬件设计方案.以射频芯片CC2420为无线收发模块,数字温度传感器DS18B20负责采集温度并发送给超低功耗微处理器MSP430F149,再经无线收发模块发送给相邻节点,完成数据监测和发送.节点具有功耗低、体积小、测量准确等特点,有良好的应用前景.
The wireless temperature sensor node is designed in order to achieve the real-time temperature monitoring. The RF chip CC2420 was adopted as wireless transceiver. The digital temperature sensor DS18B20would collect the temperature signals in environment and send them to microcomputer MSP430F149. Then the data would be sent to the neighboring nodes by wireless communication module. The temperature monitoring could berealized. The node which has many features, such as low power consumption, small size and high precision,would be used well.
