Visual alerts show when the carbon dioxide levels are getting high in meeting rooms at IBM’s IoT HQ in Munich. They use the building’s carbon dioxide sensors combined with GlowOrbs, designed and made by IBM’s Andy Stanford-Clark, to highlight when it is time to open a window.
I decided to make an “at home” version. I discovered most carbon dioxide sensors are rather expensive. The cheapest carbon dioxide sensor I found was the Rehau USB Stick Ambient Air Sensor. Not only does this detect carbon dioxide, it also detects many volatile organic compounds (VOCs) such as ethanol, alcohol, benzene etc. I discovered, and I am blaming the cat for this, it can also work as a fartometer.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
