Sensors & Breakout Boards

Discover a wide range of Adafruit sensors and breakout boards, designed to make hardware interfacing simple and reliable. Each breakout board is thoughtfully designed to expose complex sensor ICs through simple interfaces like I2C, SPI, or analog pins—making them easy to integrate into real-world projects.

This category includes temperature, humidity, pressure, motion (IMU), light, gas, current, voltage, and environmental sensors, along with interface and measurement breakouts. Many boards support STEMMA QT / Qwiic connectors, enabling quick, solder-free connections and faster prototyping.
