摘要该系统分为温度数据采集、数码管显示、无线数据发送单元和无线数据接收单元。发送端，通过单片机对温度传感器芯片进行温度采集，采集完后单片机对数据进行模数转换，转换成数字信息并通过无线模块将温度数字数据发送出去。接收端，通过无线模块接收发送端发出的温度信息，当数据接收完成后产生接收完成中断信号，单片机查询到中断信号后从接收缓冲区内读取数据，然后根据数据包协议将温度动态的显示在数码管上。本设计主要是进行无线发射和接收芯片以及单片机的选取、单片机编程、仿真与硬件调试等工作。61569

Title  Wireless temperature sensor based on CC1100                                                                 

Abstract The system is pided into temperature data acquisition, digital tube display, wireless data sending unit and a wireless data receiving unit. Sender by single chip microcomputer to temperature acquisition, temperature sensor chip single-chip analog-to-digital conversion on data collected after converted into digital information through wireless module will be sent temperature digital data. At the receiving end, through the wireless module receives the temperature information from the sender, when the data reception is complete after receive complete interrupt signal, single chip microcomputer after the query to the interrupt signal to read data from the receive buffer, then according to the packet agreement will temperature dynamic in the digital tube display. This design is mainly for wireless transmitting and receiving chip and single chip microcomputer hardware selection, microcontroller programming, simulation and debugging, etc.
