The aim of this project is to design and prototype a system aimed to help in the
implementation of a photovoltaic, off-grid electric system on a camper van. This System
will collect voltage and current data that will be stored in a microcontroller, and project
it into a small monochromatic screen. That data will also be used to decide which
source should be chosen to charge our system, either the solar panels or the car’s own
alternator.
The data obtained will be taken from various sources, either voltage dividers or Hall
effect current sensors that will need treatment to be shown in the correct manner. This
readings have values that we’ll analyze in order to stablish limits that will not damage
our microcontroller.
