摘　　要： 针对温湿度检测的重要性和日常管理的需求,基于RFID技术,结合温湿度传感器、单片机及无线射频模块制作了一种无线多目标温湿度监控系统。DHT90温湿度传感器和有源电子标签构成温湿度传感标签,Atmega48单片机控制读写器读写现场的多个温湿度值,然后通过射频模块nRF905无线传输数据,主接收器接收数据后经串口RS-232发送到监控PC机进行显示、存储。实验证明,该系统成本低、安全稳定,可以对多个温湿度目标进行远程无线监控和管理,是一种高效率的检测监控方式。 For the importance of measuring temperature and humidity and the needs of daily management, a kind of new wireless temperature and humidity monitoring system by combining MCU and sensor with RFID technology was developed. The temperature and humidity sensor tag was composed of temperature and humidity sensor（DHT90） and active label. The reader was controlled by MCU （Atmega48）to read and write the data information of the multi-tags. Then, the data was transmitted wirelessly by RF mod- ule（ nRF905 ）. After the data was received by the receiver, it was transmitted to the monitoring PC for display and storage by serial port（ RS -232）. The experiment indicates that the system is low cost, safe and stable,and is high-efficient to monitor and manage the remote multiple targets.
