摘　　要：此次设计充分利用了无线通讯的种种特点,勾勒出了一个以STC89C52单片机为核心,采用nRF905的无线通信功能来完成温度检测功能的系统。此无线检测系统的工作机理是巧妙地利用从机控制模块上的数字温度传感器DS18B20检测所处环境的温度,采用射频模块nRF905将包含温度值的数字信息发送到主机。当主机接收到从机发过来的信息后,利用LCD1602显示器显示从机所检测的温度值。得出此系统的应用范围相对较广,温度范围适宜于常温下。在此温度下的相对误差比较小(几乎为零)的结论。This design makes full use of the characteristics of wireless communication, and outlines a system of temperature detection based on STC89C52 MCU and wireless communication function of nRF905. The working mechanism of the wireless detection system is to detect the temperature of the environment based on the digital temperature sensor DS18B20 on the slave control module skillfully. The radio frequency module nRF905 sends the digital information containing the temperature value to the host computer. When the host receives the information sent from the machine, the LCD1602 display is used to display the temperature measured from the machine. It is concluded that the application range of the system is relatively wide, and the temperature range is suitable for the normal temperature. The relative error at this temperature is relatively small （almost zero）.
