I’m new to Seeed Studio, and looking to set up web enabled DC voltage monitoring for a 48v off grid battery back. Ambient temperature would be a plus as well. If necessary, I can use a Pi computer for the web functionality, as long as the hardware sensors have a way to communicate with the Pi.
Hi there, And welcome
SO I was looking at this and a lot comes up if I search for
You have several approaches you could take on it.
Super simple would be using this
provides a local display as well.
Or more complex with Voltage divider and Zener Diode using the ADC input to get a 0-4096 (assumes 12bit ADC) with arduino code.
Robot guy has some decent tutorials on this also HERE
