“In this post, we will learn how to build a simple yet useful air quality sensor. We will use the SGP30 sensor along with the Piksey Pico, though the sketch will work with pretty much any Arduino compatible board.
The video above talks you through the importance of such a sensor. We also discuss several factors that were considered when selecting the components for this project. I recommend watching it to get an overview of everything, particularly if you will be using the PCB that has been designed for this project.”
