Send Sensor’s Data to Adafruit IO Using ESP32

Another interesting IoT platform from Adafruit.

Introduction

Want to make your project talk to the Internet? Connect your existing project to the Internet to log, stream, and interact with the data it produces? What about all this Internet-of-Things (IoT) stuff?

Adafruit IO is a platform designed by Adafruit to displayrespond, and interact with your project’s data. Adafruit also keep your data private (data feeds are private by default) and secure (Adafruit will never sell or give this data away to another company) for you. It’s the internet of things – for everyone!
