摘　　要：针对不利铺设线路的环境中进行多点的温度测量与数据采集，提出了一种基于超高频2．45GHz的无线温度传感系统的设计方案。采用数字温度传感器进行温度采集，并通过无线方式与主机进行数据通信，完成数据无线通信、编解码、显示、存储等功能。系统测量范围为-10-55℃，精度可达0．125℃。最后，对测量的数据进行统计与分析，并得出相应的结论。A novel design solution based on ultra-high frequency 2.45 GHz is presented to implement a wireless data acquisition system to solve the measurement in some places where is not suitable to place the wire. The digital temperature sensor is used to collect the temperature data. They connect with each other by wireless communication and then the host decodes the data and shows them and store them. The measuring range is from -10 -55℃ ,and the minimum precision is 0. 125 ℃ At last,the measured data are collected and analyzed and some conclusion is shown.
