NFC temperature sensor / pressure sensor

edited August 6 in RFID/NFC

I found this today and thought it worth sharing:

Its a $10 temperature sensor patch which powers and transmits data via NFC. No battery, no bluetooth, just a flexable patch.

The magic behind this is the RF430FRL15xH microcontroller:

The microcontroller can be piggy backed or used in your own circuit with different sensors. Here the original temperature patch was piggy backed to add a pressure sensor as well:
