I have a project about to mantain a data log of a 3 phase motor, when the more is on and off count that time and save in memory location.
I don't use any server now to save data, I use a Rpi to do all this stuff. Any other controller I can use suggest please.
I want that 3 phase signal on my Rpi when the switch is on, 1- 3 phase AC to 3.3v dc signal? Thank you.
