Arduino

Using the SPA06-003 breakout with Arduino involves wiring up the breakout to your Arduino-compatible microcontroller, installing the Adafruit_SPA06_003 library, and running the provided example code.

Wiring

Wire as shown for a 5V board like an Uno. If you are using a 3V board, like an Adafruit Feather, wire the board's 3V pin to the sensor VIN.

Here is an Adafruit Metro wired up to the sensor using the STEMMA QT connector:

Board 5V to breakout VIN (red wire)
Board GND to breakout GND (black wire)
Board SCL to breakout SCL (yellow wire)
Board SDA to breakout SDA (blue wire)

Here is an Adafruit Metro wired up using a solderless breadboard:

Board GND to breakout GND (black wire)
Board SCL to breakout SCK/SCL (yellow wire)
Board SDA to breakout SDI/SDA (blue wire)

Library Installation

You can install the Adafruit_SPA06_003 library for Arduino using the Library Manager in the Arduino IDE.

Arduino IDE with the tools menu open and the Manage Libraries item highlighted.

Click the Manage Libraries ... menu item, search for Adafruit_SPA06_003, and select the Adafruit_SPA06_003 library:

Arduino IDE Library manager pane open with "Adafruit_SP06_003" in the search box.

If asked about dependencies, click "Install all".

Arduino IDE dialog asking if the user wants to install dependencies for Adafruit_SPA06_003 library.

If the "Dependencies" window does not come up, then you already have the dependencies installed.

If the dependencies are already installed, you must make sure you update them through the Arduino Library Manager before loading the example!

Upload the sketch to your board and open up the Serial Monitor (Tools -> Serial Monitor) at 115200 baud. You'll see the SPA06-003 recognized over I2C. Then, the temperature, and pressure will be printed out to the Serial Monitor.
