These affordable and easy-to-use temperature probes are designed to work with an app – but with a little CircuitPython, we can even read these probes into a microcontroller board for transfer over wifi, long term data storage, or analysis.

Wireless Bluetooth Low Energy (BLE) temperature sensors are a great way to do just that, and now we can use the iBBQ protocol to display multiple temperature probe values simultaneously on the CLUE’s display!

Are you doing a lot of slow cooking or smoking in the BBQ? Or perhaps you’ve got sourdough proofing on the counter and another in the oven? If so, you may find yourself looking to monitor a number of temperatures all at once.

This new guide will show you how to monitor multiple remote temperature sensor probes on the CLUE’s display using the iBBQ Bluetooth Low Energy protocol! Plus, you can run the bonus “boiling point elevation” kitchen science experiment.



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.
