RE: AC voltage and calibration - sanurss - 02-17-2024
I found a project which with almost the same hardware calculates real and apparent power.

@admin
Can we do the same on M16 v2?
RE: AC voltage and calibration - nickdd - 02-17-2024
thanks for the link, but I don't understand yet how they define the power factor.
@sanurss: also read this one about SCT013 low power accuracy: https://www.casler.org/wordpress/low-current-measurement-performance-of-the-sct013/
RE: AC voltage and calibration - sanurss - 02-18-2024
Thanks for the article, I have SCT013 clamps and according to schematics the shield is not connected...

Looking at M16v2 schematics I see some capacitor connected to the clamp but it seems to be to the ground rather between signal pins. Unfortunately it doesn't seem to be so easy to fix now.

@admin Do you have Arduino code that calculates apparent and active power as well as power factor for M16?

sorry, only have arduino Calibrate code for AC voltage.
