We found the GUVB-C31 https://www.digikey.com/short/088zdvb8 and GUVA-C32 https://www.digikey.com/short/wj29qtvr tucked in the Digi-Key catalog, these are UV sensors with true UV diodes and tuned for different spectra. We’re always getting requests for true UV sensors, and these could be useful particularly given the different responsivity. The GUVB is good for ~250 to 320nm, the GUVA is ~250 to 370nm and can output UV index as well it seems. We’ve never seen this chip used but we whipped up a quick breakout and will try it to see how well they work!
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.
