I have a battery driven touch activated kitchen faucet. I am trying to convert it to DC adapter operated one to save on batteries. First thing I tried is just hooking up a 9V 2.5A DC adapter. It kind of worked but the faucet would turn on and off erratically without being touched. I figure that electronics are sensitive to fluctuations that are not present when battery operated.
- Am I right by thinking that the erratic behavior is due to fluctuations or is it likely due to something completely different?
- If it is due to fluctuations, would the following circuit smooth them out?
- If yes, what specific diode do I need to make this work?
- Is this a common problem? I did a conversion like this for some battery powered motion sensor lights and they work but once a month they need some kind of a "reset" to work again. Could that be also related?
Note: as you can tell I'm a complete beginner at this. I kind of just googled stuff and figured out things in circuit simulator, but I have no idea what I'm doing so I would not be surprised if I'm on completely the wrong track in trying to accomplish this.
