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!
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Nice to have a NIST traceable temperature to confuse with all my other thermal sensors.
I did wonder about the slow time to acquire a reading - until I read the documents closely and realized that the TMP117 was internally averaging to reduce jitter. Easy enough to change a couple of parameters and just grab a single sample - the heck with jitter. Which of course contradicts the potential accuracy that I paid good $$$ for. Well, no one said I was consistent...
Really like the board and how Sparkfun made it easy to cut traces to change addresses etc, but the onboard LED seems like a mistake. Purchased two of these boards, ran repeated tests and found that with the LED enabled the reported temp runs about 0.25 C higher when ambient temps are ~22 C. That's a lot for a sensor with 0.1 C accuracy. I tested that on multiple Sparkfun TMP117 boards in multiple locations with and without the LED trace enabled and got consistent results. No idea if this is due to electrical effects or actual heating.
