阐述了基于无线传感器网络和GSM技术的烟雾、温度、湿度场测试系统的组建方案,以及各节点具体实现方法.测试节点的监测数据通过微控制器C8051F310经烟雾模块MQ-2、温湿度传感模块DHT11采集,利用RF1101SE实现无线上传至主控节点,主控节点通过GSM模块TC35i向农场主指定手机发送短信报警信息.系统测试表明,基于无线传感和GSM场测试系统具有实时性、易组建和易操作等特点.%A kind of field testing architecture and nodes implementation were described based on wireless sensor network and GSM in order to test smoke, temperature and moisture. Testing nodes can acquire the data through C8051F310 core module, and MQ-2, DHT11, and then upload lo controlling node by RF1101SE. Lastly, controlling node can send the specific alarm message to former's cell phone. The field testing system was real in time, easy to set and operate.
