SparkFun Temperature Sensor - STTS22H (Qwiic)

Jargon buster

Plain-language definitions for the technical terms used above.

breakout

A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny 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.

IoT

Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.

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.

ODR

ODR means output data rate: how often the sensor produces a new measurement. A higher ODR can capture faster motion or vibration, but it usually uses more power and creates more data for the microcontroller to handle.

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.
