As a motion sensor use a two band pyroelectric sensor which has exits in the form of a pair of contacts connected to the device. When it detects a moving person, the contacts of the sensor closes. On noticing human motion, a lamp(220V)(Power<500Watt) is turned on to the maximum power. 25 seconds after the person moves away from the detection zone, part of the lamp goes [login to view URL] a minute, the whole lamp goes off. When the device notices a person again, the whole cycle repeats. The lamp is controlled by two electromagnetic relays As voltage source,create a source on an integrated voltage regulator. Work should contain; 1)structural scheme diagram and description; 2)List of choice of circuit elements 3)Description of every element and time diagram 4)Caculation of resistors/transistor values 5)Principal electric scheme 6)list of elements in principal scheme

Hi there! I'm Pranav, from India. You have basically given all the details required on the project description (which is one of the most well written, I have seen here on FL, thanks!), except for a few points that we can discuss on messages or Skype. I am assembling a list of components and ideas right now, to make this proposal more exciting. Till I get that done, you could have a look at my previous projects to understand how professional and fast I am on designing and prototyping electronics projects. I have a few years of knowledge, and well, your project falls right into my domain... :) So I will update this when I'm done looking for great components for your project. A few things I will need: * Are there two lamps? One for low, the other for high? (I suggest one lamp, and PWM dimming it) * PWM dimming? PWM is turning on and off a signal fast enough, for the human eye to perceive it as varying brightness (google it!) This will require Solid State Relays, or some other active, non-mechanical, switching device. General mechanical relays wear out over time, and aren't good for fast switching. They also make a bit of noise. * Budget!!!! How much do you wanna spend on the RnD, and if its a manufacturable product, how much on the end product? I will be supplying you with all files required for Design for Manufacturing. This includes my services for: * Component selection * Schematic design * PCB Layout and routing * Gerbers for PCB fab * BoM, PnP, Component placement Dia

I'm an hardware engineer and have an experience in such a project. Ready to start now. I have some advice for your project, Relays is not the best choice, Triac will be better for it. timers will be implemented on AVR micro controller. могу говорить на русском. Regards.
