摘要
传统的温度监测系统存在布线繁琐、可扩展性差、不便维护等问题。设计一种基于ZigBee技术的无线温度监测系统,以CC2530无线射频微控制器为核心,采用数字化温度传感器DS18B20测量温度,包括2个终端节点和1个协调器节点,利用ZigBee网络将数据汇总至协调器并通过OLED显示,通过串口转WiFi模块ESP8266将数据发送到指定的服务器上,手机端通过开发的Android程序访问指定服务器查询温度数据。系统温度测量范围为0~99℃,通信距离为0~70m,经测试系统运行稳定,具有一定的应用前景。
The traditional temperature monitoring system has problems such as the complexity of wiring,poor extensibility and maintenance of inconvenience.Design a wireless temperature monitoring system based on ZigBee technology.The system is centered on the CC2530 radio frequency microcontroller.Use the digital temperature sensor DS18 B20 to measure temperature.The system includes two End Devices and one Coordinator.Aggregate the data to the coordinator and display it on OLED with the ZigBee network.The data is sent to the specified server via the serial port transfer module ESP8266.The mobile phone accesses the specified server query temperature data through the developed Android program.The effective measurement range of the system is 0 ~ 99 ℃ and the effective communication distance is 0~70 m.After testing,the system is stable and highly scalable.
