近年来，世界范围内对RFID传感器标签技术的兴趣日益增加，该技术可以获得智能卡的外部环境信息。在传感器标签的情况下，大多数传感器标签已经被开发为电阻型传感器标签。电阻式湿度传感器受温度的影响，需要进行温度修正，而且在特殊环境下检测15%以下的低湿度，为了解决这一问题，将电容式传感器与电阻式传感器标签联锁构成电路。组成的电路是一个电容式湿度传感器，它连接到电阻式传感器标签。采用CVC电路，电容式湿度传感器改变的是输出电压。输出电压与电阻式传感器标签连接。实现了系统的传感器值存储或真实的时间监测实验结果能够确定有用性。此外，开发的湿度传感器标签应用于智能冰箱。
Recently, interesting about RFID sensor tag technology which can obtain information on the external environment to smart card is increasing worldwide. In case of sensor tag, most of sensor tag has been developed as resistive type sensor tags. Resistive type humidity sensor requires temperature revision as the influence of temperature and there are special environment to detect low humidity of 15% or less. To solve this problem, circuit was composed that capacitive sensor is interlocked to resistive type sensor tag. The composed circuit is a capacitive humidity sensor which is connected to resistive sensor tags. Using the CVC circuit, capacitive humidity sensor change is output voltage. The output voltage connects with resistive sensor tag. Implemented system's sensor value storage or real time monitoring experiment result was able to determine the usefulness. Also, developed humidity sensor tag is applied to the smart refrigerator.
