SparkFun Digital Temperature Sensor - TMP102 (Qwiic)

The SparkFun Digital Temperature Sensor - TMP102 (Qwiic) is a small, easy-to-use board for adding accurate temperature readings to your project. It is built around the TMP102 from Texas Instruments and reports temperature digitally over I2C.

The sensor has 12-bit resolution (0.0625°C steps) and a typical accuracy of ±0.5°C. Two Qwiic connectors let you plug it into a Qwiic or Stemma QT system without soldering and chain it with other boards.

The default I2C address is 0x48, and three more addresses are available, so you can run up to four TMP102 sensors on one bus. The 0.1" pins also let you use the board on a breadboard.
