NEW GUIDE: Adafruit SCD-40 and SCD-41 #AdafruitLearningSystem #Adafruit @adafruit
CO2 sensing over I2C in a tiny package!
The SCD-40 and SCD-41 are photoacoustic ‘true’ CO2 sensors that will tell you the CO2 PPM (parts-per-million) composition of ambient air. They really are measuring the CO2 concentration! That means they’re bigger and more expensive, but they are the real thing. Perfect for environmental sensing, scientific experiments, air quality and ventilation studies, and more.
The new Adafruit SCD-40 and SCD-41 guide covers everything you need to know to get measuring with your SCD-4x sensor. There’s an overview, detailed pinouts page, examples in CircuitPython and Arduino, and resource downloads.
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. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
