thanks . But this is project I can't buy a production that can do at all.
Because this project is studying.
- I think. If I use some resistors that's parallel with load (ac) then I use a rectifier to conver ac to dc and put into ADC of microcontroller. So I can measure Volt of the Load.
- With current ac, I use a sense resistor (1 Ohm). I solve it same about.
the Ohm law (I = U/R). I measure the current.
- But how a bout cos (pi) , and total power on the Load ?
All that's measured will be translated into Master (computer) on the RS485 network.
- I have some picture that's suggest a little but I am not sure.
Please tell me your point about It . thanks
