    Good morning,
    I’m interested on the UHF RFID tags that you offer, but i have some questions about them.
    First of all, which is the difference between the RFM2100 Moisture sensor and RFM2120 Moisture sensor for healthcare ?

    Second, i read that the chip present in your tags is able to tune the reactance at its port in order to compensate for a mismatch with the antenna, and then sends a 5 bit sensor code, corresponding to the amount of un-tunning in the antenna.
    – Is this right?
    – How can i parse the backscatter information to get the sensor data?
    – Do i need a particular reader or program?


    My current setup is SparkFun Simultaneous RFID Reader – M6E Nano connected to an arduino, and a 6dB antenna.

    Hope you can help me.
    Thank you.
