Overview

Knowing what's in the air you breathe is important - and building an environmental monitor is a way to visualize the invisible properties of the air you inhale.

This guide covers building a small, internet-enabled environmental monitor which can track a range of data such from temperature to UV-level to the amount of total-volatile-organic-compounds present in the air.

Build it, place it in a location you'd like to log, and then monitor it from anywhere in the world using our Internet-of-Things platform - Adafruit IO.

This project can be done with either Arduino or CircuitPython, too!
