Overview

Use sensor-packed Bluefruit boards and a Raspberry Pi to build a network of sensors that send data to Adafruit IO!

This project takes advantage of CircuitPython running on the Feather Bluefruit Sense and CLUE boards (any nRF52840 Adafruit board will work) and Python running on the Raspberry Pi.

The Pi receives advertised BLE sensor data from the Feather and CLUE and then sends that data over WiFi or Ethernet to your Adafruit IO feed.

Its a super easy way to make a wireless sensor node, using the built in wireless/networking capabilities of the Raspberry Pi!

Parts

You can use any of the Adafruit nRF52840 boards and sensors you like. We'll show how it works with the Feather Sense and CLUE boards, since they pack so many sensors right on board.
