Most UPS have a line that goes high when the UPS delivers the power.
Depending on the voltage it provides you must use a voltage divider (or better opto-coupler) to connect it to the Arduino.
The Arduino can start a timer (e.g. 15 minutes) and if the UPS does not switch back to mains you could activate a relay that switches off the PC.


Hello everybody!
Shields Easyvr bought 2, and I love the interaction with the commands, I am still practicing.

I have a question, it will be with EasyVr, you can read, for example:
Making the Shield speak loudly at room temperature with the aid of a module temperature?

Or even tell the time, based on clock module, connected to the Arduino?

Or he speaks what sereal monitor displays?

Thanks for listening, I'll be waiting for the answer.
