Hello!
I need to realize a reliable proximity switch - on/off for 100W bulb with soft start.
I have some circuits with metal plate as a capacitive sensor but maybe the optical sensors are more reliable and easy to realize.
The main problem is to overcome false triggering. The best solution for that is maybe to use a PIC micro with an inteligent algorithm.
Another problem for me is the soft start. How to realize it?
Please help if you have any ideas or schematics!
