TIDM-RF430-TEMPSENSE: Use Case Investigation of Temperature Sensor Patch in the UHF (~865MHz) frequency range

Part Number: TIDM-RF430-TEMPSENSE
Other Parts Discussed in Thread: RF430FRL152H, CC1101, TIDA-00721

Dear All,

I am working on a proof of concept for a use case involving the integration of this 13.56MHz  temperature sensing patch into an application operating in the UHF (~865MHz) frequency range. Is it possible to help me re-design this for UHF please?

Best Regards,

Kieran

    Hello Kieran,

    We do not have a UHF RFID product offering and the RF430FRL152H will only operate at 13.56MHz levels.

    The general theory behind a temperature sensor over RF could be applied with products from other companies that support UHF RFID. For example you can see how this TI design was handled and replace the NFC interface with UHF: http://www.ti.com/tool/TIDA-00721

    We do have a few devices like CC1101 which can communicate at UHF range, but do not have UHF RFID specific implementations available for them and trying to implement UHF protocol would be up to you.

    Hi Ralph,

    Thank you for the information - it is much appreciated.

    So, can you please just confirm my understanding is correct? Basically, we could take the TIDA-00721 design and replace the NFC interface using the CC1101 (or similar) UHF design?

    Regards,

    Kieran.

    Hello Kieran,

    In theory, yes. I'll be very forthcoming though, you are likely better off using a non-TI product for the UHF interface in order to get something that actually implements the UHF RFID protocols natively. We have mentioned CC1101 in the past, but I have not heard of anyone who actually returned afterwards to say that they have succeeded with that implementation.
