I need to detect the passage of the mains voltage to zero due to the power control using the MCU .
I am looking for a reliable, cheap and small ZCD .
I would like to use AC Optocupler PC814 with two small 1k SMD resitro 1206 + two SMD 100nF X7R 500V 1206 capacitor.
Power consumption ia only 35mW.
Yes, the endurance is only 1000V, but when you put it on, there is an insulating barrier for the optocoupler.
Do you consider this a good idea?
