What do you want to monitor?
1. Presence of 230V AC. 2. Measure the voltage. Also, is this 230VAC that you want to detect/measure also the power source for your equipment? If it is, then you just need to measure the output of your mains transformer - and detection is even simpler! (you will need some sort of battery backup, of course...) |
