Dust is one of the more difficult workshop dangers. We don’t just mean little flecks of dead skin that float around and coat old equipment, but tiny fragments of almost anything that float through the air and settle in our lungs. Some dust is well-known to be particularly dangerous – most famously asbestos – but almost all dust is dangerous to some extent.
Small particles aren’t visible to the naked eye, and if they make their way deep into the lungs, they can be difficult for our
bodies to remove.
We’ll be using a PMS5003 air quality sensor which is fairly common. It outputs data using the common serial protocol, so you should be able to get it to work with most microcontrollers, and we’re using an Adafruit Metro ESP32-S2 Express, as this works with both WiFi and CircuitPython, making it a great choice for Internet of Things-type devices.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

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.
