摘要
传感器节点主要由CC2530射频模块、温湿度传感器DHT21、GSM模块以及串口上位机组成。以CC2530射频模块为系统的控制核心,在发送端模块负责采集温湿度传感器信号,通过RF射频端把现场的信息传送到接收端的CC2530模块,接收模块把接收到的温湿度数据通过串口通信把数据传送到上位机中,从而实现现场温湿度数据曲线的显示。GSM模块通过串口直接与上位机通信,该模块能通过手机通信网络把温湿度以短信的形式发送到指定用户的手机中,从而实现物流货品信息的远程监控。
The sensor node includes mainly CC2530 Radio frequency（RF） module,temperature and humidity sensor DHT21,GSM module and the serial PC.The CC2530 RF module is the core component of the system.The module at the sending end collects the signals from temperature and humidity sensor,the temperature and humidity information are transmitted to the CC2530 module located at the receiving end by using RF module.Lastly,the measured signals are sent to the monitor PC through a serial communication channel,and displayed on the screen.The GSM module can directly communicate with the host computer via serial communication channel,and all the monitored data can be sent to the specified mobile phone through the mobile communication network.The system can monitor the state of containers remotely.
