I just acquired an ADC Pi Plus for air quality measurement and was wondering whether I can use the same ADC Pi Plus to monitor the voltage coming out from the battery powering the Raspberry (my goal being to shut down the pi properly when the battery level is getting low).
Is that possible?
Given that my battery provides power up to 5.6V, I assume I need a voltage reducer between the battery and the ADC Pi Plus? Would you know of a reducer that I could use? Ideally, I would like to avoid using a breadboard as I am trying to build an integrated solution.
The battery output is USB.
