Hi! I'd also be interested in such a circuit. I could imagine a ds2438 (battery voltage sensor) or ds2450 (quad ad) in combination with some trimpot that gets operated by some of the mechanics (I think that this is the harder part, not the soldering :) My door uses an electrical opener (24V DC, 10mA), which I operate using a relay and a ds2406. The other port of the ds2406 is connected to a micro switch, that gets touched when the door is fully closed. I thought about adding another ds2406 to "see" if the door is fully opened, so I can detect moving states (i.e. not closed and not open = moving). br, Markus ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
