摘要:单片机是指一个完整的计算机系统集成于一块芯片。它大大的部分职能整合对蛋糕大小的小芯片，但也有很大的部分能满足一个完整的计算器需求：CPU，存储器，片内一部分和外部共线系统，组合的一部分，也有外界以节省芯片存储空间,在此期间，如通讯连接，在固定的时间机器，实际上始终时钟等现在最强大的单一切片机系统甚至可以语音，图片，网络，复杂的输入输出系统集成于一块芯片。

　　本文介绍的是一个由单片构成的无线温度控制系统，系统首先单片机进行温度采集，然后进行无线发送，之后显示温度显示，它采用STC89C52单片机和DS18B20以及NRF24L01等其他器件实现。该系统具有准确度高、实时性好、功耗小、价格低廉等优点，具备商业应用价值。

Abstract:The single slice machine means a complete calculator system which integrates on a piece of chip. Though he greatly parts of functions integrate on a cake of small chip, but it has greatly parts of parts that a complete calculator needs: CPU, memory, inner part and the exterior total line system, greatly part of will also have an outside to save currently. Integrate in the meantime such as the communication of connect, in fixed time machine, actually and always clock etc. peripherals. But now the most strong single slice machine system even can voice, picture, network, the complicated importation output the system integrate on a piece of chip.

　　　An applied system of wireless tempcrature control by microcontroller is introduced in this paper. First,the microcontroller takes in the temperature, then the signal is transmitted, when the receiver receives the signal, the temperature is displanyed with the monitor. It uses STC89C52, DS18B20, NRF24L01, LCD1602 and other components to realize. The system has good performance in accuracy, real-time, power, costetc and commercial applications.
