摘要
利用温度传感器DS18B20、AT89S51单片机和nRF2401收发芯片设计分布式无线温度测试系统。将温度传感器DS18B20采集到的温度数据送入单片机中进行处理,通过nRF2401实现远程数据的传输,采用USB接口与PC机进行高速通信,从而实现实时监测环境温度的功能。本系统在室内传输距离为50m左右,室外可达100m,具有一定的实用性。
The distributed wireless temperature test system was designed by using temperature sensor DS18B20, MCU （Micro Controller Unit）AT89S51 and single chip transceiver nRF2401. DS18B20 was used as a temperature sensor, and the temperature data was acquired by microprocessor for processing and long-distance transmitting by nRF2401. This system used USB interface to the high-speed communication with PC, realizing the purpose of real-time monitoring. The distance of transmission indoor was about 50 meters, up to 100 meters outdoors; this system had a high practicality.
