How to Make a Slick Tech Cube for Air Quality #CitizenScience #Arduino #DIY #environment

The term air quality monitor really doesn’t do this build justice. This is Marc Finn’s Atmoscan—an epic monitor in a cube that will gather almost anything you can imagine in your surroundings and spit out readings on a gorgeous LCD color display. The device will get you temperature, humidity, barometric pressure, PM1.0, PM2.5 and PM10 for starters. It will also give you data on CO2, CO, NO2 and VOCs. However, what’s really impressive is that it also detects radiation.

Marc spent considerable time testing sensors, creating a custom board with an ESP 12-E, and figuring out a workaround for memory space for the graphics. The result is not only data from sensors, but data from services like Weather Underground and Plane Spotter.  Along with the good looks, this device is gesture controlled. In fact, the acrylic layer on the top of the cube had to be thinner in order for the gesture sensor to function. Marc has ideas for improvements, but for now the project is entered in the Epilog Challenge 9 contest at Instructables, which is appropriate since the winner receives a laser cutter (wouldn’t that be great for future cubes). So far there has been a ton of interest on this Instructable and Marc has actually been mailing out his extra boards. He claims he doesn’t have the time to pursue a KickStarter, but perhaps others will take up the cause since this is a project that deserves to be expanded. If you would like to learn more about sensing particulate matter, check out our learning guide for the PM2.5 Air Quality Sensor. You’ll discover how the sensor functions and find test code for Arduino and CircuitPython. Be empowered to explore your environment.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email to let us know about your post so we can blog it up here.

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, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
