I published a small command-line tool to read the Sensirion SGP30 air-quality sensor on a Raspberry Pi. I explain usage, options, and how to build and install the C tool so you can get JSON CO2/TVOC output. If it helps, please read the full post for details.

I guide you through building a compact particle sensor node using a Raspberry Pi Zero W and a minimal custom shield, with published Gerbers, STL files and example code. I keep the design simple and extendable—if you'd like to build your own networked air-quality node, read the full post for parts, assembly and setup.
