Have you ever wondered what the air quality is around you while you’re out and about? With this project, you’ll be able to monitor CO2 levels and log them, like an IoT device, but without having to worry about connecting to a network. This means you can collect data from places like public transit, concert venues or even on your bike ride.
The guide will show you the basics of using CircuitPython to log sensor data to an SD card and utilize a real time clock. Additionally, you’ll learn a lot about the air quality around you.
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.
