This release provides a complete and tested Arduino sketch to monitor solar panel voltage and current in real time using the ACS712 current sensor and a 16x2 I2C LCD. The code is written for ease of ...

This is an example of measuring electrical power using the zmpt101b sensor for voltage measurements. There are also examples for calibrating the sensor itself (with the Arduino IDE serial plotter) and ...

The versatile device has been designed for up to 30V, 5A, and 15W. It was based on a constant current source that is controlled by a DAC hooked up to the Arduino.
