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 on-board 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.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you canÆt hook it up wrong.
