Description

TIDA-00721 is a complete reference design for accurate temperature measurements using a passive NFC tag in a flexible patch form factor. The system offers temperature readings from tag to a NFC receiver such as a NFC enabled smartphone. The high accuracy temperature sensor (LMT70) is interfaced with an ADC (ADS1113) and the temperature data is sent to the reader with the NFC transponder (RF430CL330H).

Features
  • Human skin temperature sensing patch design
  • Temperature data transfer with NFC interface
  • Integrated PCB antenna
  • Probe contacts for programming or troubleshooting
