# CircuitPython BLE Multi-Temperature Monitoring ## Overview https://youtu.be/meGmEZ3bvBA ![](https://cdn-learn.adafruit.com/assets/assets/000/090/212/medium800/temperature___humidity_bbqlue_action-1592.jpg?1586295879) 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. 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! 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. ## Parts ### Adafruit CLUE - nRF52840 Express with Bluetooth® LE [Adafruit CLUE - nRF52840 Express with Bluetooth® LE](https://www.adafruit.com/product/4500) Do you feel like you just don't have a CLUE? Well, we can help with that - get a CLUE here at Adafruit by picking up this sensor-packed development board. We wanted to build some projects that have a small screen and a lot of sensors. To make it compatible with existing projects, we made...
