  • RF Backscatter Sensor for Measuring Moisture and Other Biological Data
    Publication number: 20140358099
    Abstract: A moisture sensor unit for sending moisture in an environment includes a passive moisture sensor and two passive RFID tags. The two passive RFID tags are spaced apart from each other and disposed on opposite sides of the moisture sensor. Each of the RFID tags is electrically coupled to the moisture sensor and each of the RFID tags includes a circuit that determines an amount of moisture that is associated with the moisture sensor. Each of the RFID tags is configured to respond to a first radio frequency signal with a second radio frequency signal that includes information about the amount of moisture.
