Explanation

This code give the values read by the ESP32.

How to use

This code will give to you the Voltage, Current and Real Power read by the ESP32, so will give values in the interval 0 to 3,3.

So its recommended use diffent values of voltage and current, to build a sample data for a linear regression.

Example:

Voltage applied: 0V - Voltage read: 0.02501

Change the applied voltage to 20V, and press the "EN" on the esp32 board. With that, a new voltage read should be printed in the screen.

Voltage applied: 20V - Voltage read: 0.16401

So each time that you want to generate a new sample, the setup function should be executed by pressing the "EN" button on the esp32. This should be done to the current and the real power.
