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.
