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 can’t hook it up wrong.

The TMP117 High Precision Temperature Sensor can also be automatically detected, scanned, configured, and logged using the OpenLog Artemis datalogger system. No programming, soldering, or setup required!
