## What it is
Adafruit Unified Sensor is an Arduino/C++ abstraction layer providing a common Adafruit_Sensor base class and standardized sensors_event_t data types in SI units. It lets interchangeable sensor drivers (accelerometers, gyroscopes, temperature, pressure, etc.) be swapped with minimal code changes.

## Use cases
- read accelerometer data on arduino with a unified api
- swap sensor models without rewriting embedded code
- log sensor data in standardized si units
- build a portable arduino sensor driver
- unify temperature humidity and pressure sensor readings

## When to choose
- writing Arduino sketches using Adafruit sensor breakout boards
- you want sensor-agnostic code that survives hardware changes
- building data-logging or telemetry with a single well-known sensor type

## When to avoid
- using non-Adafruit sensors with their own native drivers
- bare-metal projects outside the Arduino ecosystem
- you need direct register-level control of a specific sensor

## Facets
- artifact type: library
- maturity: stable
- function: sdk, embedded, middleware
- domain: embedded-systems, hardware, iot
- platform: embedded, cpp, iot
- tags: arduino, sensor-abstraction, adafruit, sensors-event, si-units
