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, from temperature to UV-level to the amount of total-volatile-organic-compounds currently present in the air.
Build it, place it in a location you’d like to monitor, and then view it from anywhere in the world using our Internet-of-Things platform – Adafruit IO.
The best part? This project can be performed with Arduino or CircuitPython. We have full build and code instructions for the Raspberry Pi and Arduino-compatibles.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
