This is really a cool little device that not only allows you to measure current, but voltage as well. With a little multiplication, you can even measure power.
In terms of voltage, you get to blow right past the Arduino 5 volt limitation. In fact, you can measure up to 26 Volts DC.
At +/- 3.2A, current measurement range is suitable for most smaller measurements. In other words, you can measu...

<p>Trying to implement a module that charges a leisure battery in a car when the engine is turned on. This module will detect the voltage to determine the engine state and will try to charge the leisure battery at a current of ~30A. It features a simple buck converter based on a BTN8962 power switch...
A generic i/o board for my RV, includes the following:
