The SparkFun STTS22H Micro Temperature Sensor is a Qwiic-enabled breakout board based on the ultralow-power, high-accuracy, digital temperature sensor STTS22H from ST Microelectronics and housed in our Qwiic Micro form factor. Thanks to its factory calibration the STTS22H offers high-end accuracy performance over the entire operating temperature range, reaching as low as ±0.5°C without requiring any further calibration at the application level.
The sensor operating mode is user-configurable and allows selecting between different ODRs (down to 1Hz) or the one-shot mode for battery saving. In one-shot mode, the sensor current consumption falls to 1.75µA. Peripheral addresses are also user-configurable and allow up to four different addresses to be specified by manipulating the jumpers on the back of the breakout. In addition, an interrupt pin is available to signal the application whenever the user-selectable high or low threshold has been exceeded.
Hook-up is a breeze as the breakout board uses the Qwiic Connect System. The breakout board has built-in 2.2kΩ pullup resistors for I2C communications. If you’re hooking up multiple I2C devices on the same bus, you may want to disable these resistors.
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.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- NIST traceability
- A way of linking a measurement back to standards maintained by the US National Institute of Standards and Technology. For temperature sensing, it matters when you need documented confidence that readings can be compared to recognised measurement standards.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
