Industrial Internet of Things Tools

This repository tries to keep order on many Industrial Internet of Things (IIoT) code examples using Arduino IDE as the main software development and the ESP32 as the hardware device. Also there are some examples using Node-RED as a way to show full integration with a gateway and its communications.

Each of the referenced examples will consist of a simple code in Arduino IDE format .ino that will try to auto-explain the way you can reuse the code in other and more complex projects. Sensors and outputs will also contain information about the datasheet and its connection scheme to the ESP32.

All the examples are ordered in the following groups. Navigate through them and try them all!
