Hello,

I am new to this forum?

I have to calculate Power Factor of Load(AC Signle Phase Induction Motor, Incandescent Bulb, Energy Saver) on arduino.

Kindly guide me?

I have researched on google what I understand is:
1) Power Factor can be measure using the angle difference of voltage and current waveform.
2) Angle difference of voltage and current waveform can be measured using Zero Cross Detector of both waves.

How can I measure power factor accurately?
