If they only relied on the sensor it would constantly turn on and off which is something I have never seen on that kind of faucets.
I think there is always a delay before shutting down but sometimes that delay is set so low that it feels like you need to constantly activate the sensor.
Why not both? Automatically sense when to start your limited time.
Isn’t that how every automatically sensing faucet works?
I think typically they only turn on when they actively detect something near the sensor. Once they no longer detect the object, they shut off.
I don’t think so.

Which is exactly what I see all the time.
This one does that, it stays on only when I move my hands.
That’s how this one works. If I stop rubbing my hands the water stops. It detects motion, not proximity.
