吊瓶和药液被传感器所测重。随着药水的减少。重力传感器获得的数据用 zigbee传递给该程序后，对数据进行处理形成百分比转化为液面信息和药水滴完所剩余的时间，并将数据存入指定文件中，通过局域网链接，使得上手机端上能都看到液面和所剩时间，并液面快将为0时在电台平提示护士换药或者停药。-The bottle and the liquid is measured by the sensor weight. With the drops of medicine. Gravity sensor to obt

使用CC2530读取SHT20传感器的温湿度数据并发送或串口打印(This program get temperature and humidity data by SHT20 and send data though cc2530 with wireless or usart.)

zigbee终端连接各个传感器测得数据，然后将数据传输给协调器(ZigBee terminal connects the data measured by each sensor, and then transmits the data to the coordinator)
