Plotting CO2 levels with the Pimoroni Enviro+ FeatherWing & Adafruit SCD-30 #Feather #CircuitPython @Instructables

Kevin J Walters posts on Instructables:

In 2020, there was an increased interest in carbon dioxide levels inside buildings and enclosed spaces as it serves as a good indicator of poor ventilation, air-conditioning recirculation and overcrowding.

The Pimoroni Enviro+ FeatherWing has a wide range of sensors onboard. This FeatherWing board uses most of the pins on a Feather board but the I2C bus offers an easy way to add more sensors like the Sensirion SCD-30 for measuring atmospheric carbon dioxide.

This short article shows how to connect the Adafruit SCD-30 to an Adafruit Feather nRF52840 Express and an enhanced Pimoroni plotter program.

See the video below and the post on Instructables.


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, 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.
