摘要
针对传统温度检测系统中有线数据传输方式存在布线复杂、成本高等问题,设计了一种基于AT89S51单片机、数字温度传感器DS18B20和无线射频收发芯片nRF905的无线温度检测系统。该系统利用DS18B20测量现场温度,通过nRF905完成无线数据传输,利用AT89S51实现对温度数据的处理以及与计算机的通信,从而实现了多点温度数据采集和远距离无线传输。
For problems of complex wiring and high cost of wired data transmission mode of traditional temperature detection system,a wireless temperature detection system was designed based on AT89S51 microcontroller,digital temperature sensor DS18B20 and radio frequency transceiver chip nRF905.The system uses DS18B20 for site temperature measurement,completes wireless data transmission by nRF905,and uses AT89S51 for data processing as well as communication with the computer,which achieves multipoint temperature acquisition and long-distance wireless transmission.
