Adafruit is celebrating Lunar New Year🐍 Wednesday 1/29/2025. In combination with MLKDay, shipping could be delayed. Please allow extra time for your order to ship!
Here is a jolly cute Bluetooth-enabled sensor-and-digital-clock to monitor your room’s temperature and humidity. Only 110mm x 55mm, we dig its medium-size form factor and minimal design.
The shell is made of durable ABS material. Upfront you get a 3.5″ x 1.25″ (87mm x 32mm) eInk display. These sensors are sold to work with the Mijia “Mi Home” App (iOS and Android) – they emit the measured humidity and temperature over Bluetooth LE up to about 10 meters away.
And while it’s totally fine to use it with the Mi app, we like this more for its use cases in general home automation and sensing projects!
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 7:30pm ET! To join, head over to YouTube and check out the show’s live chat and our Discord!
