Guide Updated: PM2.5 Air Quality Sensor #AdafruitLearningSystem #Adafruit #CircuitPython @Adafruit
We’ve updated the PM2.5 Air Quality Sensor guide to include Python usage on Raspberry Pi using PySerial! The updated Python & CircuitPython section now includes wiring diagrams for using a USB-to-serial adapter cable, and a Raspberry Pi. The example now includes the code necessary to use the PM2.5 on a computer as well as a microcontroller.

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.
