Design files

Overview

This reference design demonstrates highly accurate sensing of skin temperature using the TMP119 high-precision digital temperature sensor with the CC2340R5 wireless MCU. This design provides design guidance for skin temperature measurement in medical and wearable applications along with an evaluation software and smart device application.

Features
  • High-accuracy (±0.08°C) human body temperature measurement
  • 2.4GHz wireless MCU with Bluetooth® Low Energy 5.3
  • Integrated PCB antenna
  • Flexible PCB design
  • Up to three years of shelf-life plus five days of active time with a 5.5mAh coin-cell battery
  • iOS® and Google Play® apps for device monitoring
