Thank you all of you gays,
My question is referred to simply sense the presence of my AC voltage. I am searching for a circuit that will provide me the presence of AC voltage with lets say 5 volts output that I could be connected to an INT of my 8051. I had used a circuit with 1 capacitor 0.1ì 630V and 1 resistor in series connected to an optocoupler. This circuit was really nice but rather big for my application. Do you have any other advice or circuit with real values? br APA |
