SparkFun Digital Temperature Sensor Breakout - TMP102

SparkFun's TMP102 Digital Temperature Sensor Breakout is a user-friendly, high-precision tool that brings the power of Texas Instruments' TMP102 sensor to your Arduino project. Unlike many temperature sensors that rely on analog voltage, the TMP102 uses the I²C bus for communication, simplifying setup and integration into your existing project.

The TMP102 sensor boasts a temperature reading resolution of 0.0625°C and an accuracy of up to 0.5°C. The breakout comes with built-in 4.7kΩ pull-up resistors for I²C communications and is designed to operate between 1.4V and 3.6V. Thanks to the open drain signaling of I²C communication, there's no need for level shifting.

This sensor is ideal for a wide range of applications. Whether you're creating a weather station, a home automation system, or a complex scientific experiment, the TMP102 can deliver the precise, reliable temperature data you need. Its high resolution and accuracy make it perfect for sensitive applications where even a small temperature change can make a big difference.

One of the standout features of the TMP102 is its ability to support up to four sensors on the I²C bus at once. This allows for multi-point temperature reading within a single project, opening up new possibilities for complex, data-rich applications.
