I thought that since I was starting to program AVR chips this would be a nice project. Its an ac power meter, but I dont understand how it would work.
I have a clamp meter that measures current. I measure the current the multiply by 120, or what ever voltage the appliance is rated for.
This circuit uses opto isolators and op amps.
Can someone explain how this circuit works, well just the measuring part.
I just found one more circuit, both are based on the same previous circuit."Optical Isolator Computes Watts”
