SparkFun High Precision Temperature Sensor - TMP117 (Qwiic)

The SparkFun Qwiic TMP117 breakout is a high precision temperature sensor equipped with an I²C interface. It outputs temperature readings with high precision of ±0.1°C across the temperature range of -20°C to +50°Cs with no calibration and a maximum range from -55°C to 150°C. The SparkFun High Precision Temperature Sensor also has a very low power consumption rate which minimizes the impact of self-heating on measurement accuracy. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

The SparkFun High Precision Temperature Sensor also includes programmable temperature limits and digital offset for system correction. While the TMP102 is capable of reading temperatures to a resolution of 0.0625°C and is accurate up to 0.5°C, the onboard TMP117 is not only more precise but has a 16-bit resolution of 0.0078°C!

To make this breakout even easier to use, we've written an Arduino library to help you get started "Qwiic-ly." Check the Documents tab above for more information.
