Aimed at the requirement of high-accuracy measuring and wireless transmission of temperature, this paper presented a wireless detection temperature measuring instrument based on the AVR single-chip processor. The system combined nRF905 with Atmegal6L,and took DS18B20 as the temperature sensor, it achieved wireless short-range and multi-point temperature measuring system,the acquisition temperature data collected by the system were transmitted to host computer that implemented functions of data active display,query and storage. It' s indicated that the system exhibited the features of low-cost,easy to extensity and convenient to operation, and can be widely used to detect temperature and transform data in industrial environment.%为了满足当前温度采集系统对于温度进行精确测量、无线传输的需求,文中提出了一种基于AVR单片机的无线测温系统设计方案.测温系统以nRF905无线芯片和单片机Atmega16L为核心,采用单总线数字式温度DS18B10进行准确测温,实现了短距离无线传输和多点温度的精确采集,将采集的温度数据发送至上位机,实现了对温度数据的动态显示,查询、储存等功能.该系统具有成本低、易于扩展、用户界面操作简单等优点,可以在各种复杂的工业现场高效而准确地进行数据采集和无线传输.
