Protocol for an Arduino based UPS
Hi,
I'm building a DIY UPS for a Raspberry Pi using a 12V SLA battery, charger, and
an off the shelf 5V regulator. To monitor the battery level I'd like to use an
Arduino or similar type device. Since the Arduino can have a serial over USB
connection with the Pi I'd like to implement a protocol that can be used with NUT.
Does anyone know if something like this has already been done?
