The TMP102 is an easy-to-use digital temperature sensor from Texas Instruments. The TMP102 breakout allows you to easily integrate the digital temperature sensor into your project. While some temperature sensors use an analogue voltage to represent the temperature, the TMP102 uses the Arduino I2C bus to communicate the temperature. Of course, this is a very handy sensor that does not require much setup.
The TMP102 can measure temperatures with a resolution of 0.0625°C and is accurate up to 0.5°C. The breakout has built-in 4.7k? Pull-up resistors for I2C communication and runs from 1.4V to 3.6V. I2C communication uses open drain signaling, so no level shift is required.
