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

Hello, I'm an electronic engineering undergraduate an I have good experince in electronics and micro controller programming. I have used atmel, PIC and arduino to builed control systems. I have good electronics knowledge too. So as I understand the your problem description I feel comfortable doing this project. I can design circuit that can handle this task and simple microcontroller program to handle the task. Another thing as I have used motion sensors so many time for my academic projects such as creating robots and much similar Lamp project to this. So If you are interested please contact me. I would like to know more information on this project. Thank you.

Hi! I'm Pranav, from India. I had bid on the other project as well, with a longish proposal, saying how well I am suitable for this project. Here I will cut all that and jump to all that I have found out since the last proposal. A three legged PIR sensor, paired with a BISS0001 IC will give you a timed response based on the motion. This is by far the best method to use for motion detection, and get a timed response as it is cheap and simple, and trustfully works in a million applications. The output from this IC can be fed to one relay, controlling the HIGH brightness bulb, and to a NE555 IC, timed to trigger for 1 minute. So once motion is detected, the BISS IC sends a high pulse to the NE555 and the HIGH bulb relay. Once it goes off, the HIGH bulb turns off, but the one connected to NE555 output stays on for a duration of 1 minute. Sounds simple, and is simple, also cheap and reliable. I had mentioned PWMing and non-mechanical switches, but that will increase the costs a bit. It depends on how much you want to spend. I will be giving you the following services: * Component Selection * Schematic design * PCB layout and professional routing (keeping high voltage and current traces in mind) * Design for manufacturability: BoM, PnP, CPD, gerbers * All calculations and timing diagrams. * Minor tweaks within a week * Endless support The project will be delivered to you within 48 hours. With warm regards, Pranav

I can develop a PIR sensor based lamp controller as you describe in 10 days. I have BS, MS and PhD degrees in Electrical and Electronics Engineering from one of the most reputable universities in Turkey and have 15 years of analog and microcontroller based systems design experience (both hardware and firmware) and 5 years of RF design experience. I am founder and manager of an R&D company focusing on analog and embedded systems design.

I recently have the same project. I use my project in my garage. When the sensor senses motion it will turn on the light. After 2 minutes without motion detected the light will turn off. I can modify my schematic to meet your project requirements.

Hello, Brother I had did this project before... I can easily send to working schematic proteus...etc.... Its not too much difficult task... only you need to controll PIR motion sensor signal with Relay... like H-Bridge... or if you wanna use Microcontroller like PIC... then you can add more function on it.... If you wanna discuss this project more then ... reply me in pm... Regards, King Ali
