Dear friends, you all know, 'hygien' is most important when using taps,bathrooms etc. People wish hygien equipments used here like electronic faucet, electronic urinals, paper dispensers etc.
You know most of them working IR sensors. But it isn't a best solution. Because some of these devices have big working errors. Even some have sticker like ' Plese, don't install sunny places '
For a super IR sensing device must have ;
1. Low current and sleep mode when not using. Because of battery life.
2. Good IR distance stability don't varying by daylight or light.
3. Functions Can be adjust by a IR remote control. For example, turn off when cleaning lavatory.
4. Output must drive a bistable valf. ( A bistable valf needs nearly 30 ns pulse for turn-on and off )

That' all. Please, don't think, i need such a circuit. I wrote this message, after when REGO inform me as RED
Dear REGO, would you please make this message a sticky?
