This is a forked version of Jared Wolff's Particle Squared Hardware. For more information on that board, visit his website. To support him and his work, you can order his sensors from here.

Particle^2 (pronounced Particle Squared) is a circuit board that helps you monitor the air quality around you. I call my fork of the project "Bare Bones" because I removed the air particulate sensor. It can still monitor humidity, temperature, eCO2 and TVOCs.

I also made some minor changes to the project to suit my goals.

This project was designed using Autodesk Eagle.

The Eagle-Renders directory contains PDF and PNG renders of the schematic and board layout.

Here is a shared project on Mouser for the BOM for one PCB.
