automatic door lock

Dear sir, I have more than 5 years in digital design and i can do this project using several methods including mobile bluetooth also i can add character LCD to display the status Like " Locked " or " UN-Locked" also i will use simple low cost board that is ready to use so you will have the design ready in no time

Hello Sir, I am Electronics Engineer, working as Embedded System Developer and PCB Designer. Since 2007 I have been into this field after my graduation. I have done many projects on Embedded System and Radio Frequency and have designed lots of PCBs of various aspects. Here I must mention that this can be accomplished simple by using Radio Frequency. Means while sitting in a room or car you can remotely open or close your doors. The number of channels on the remote control depends upon you how much devices you want to control. I will design purely an analog electronic circuit based on RF technology. Every door or appliance will be equipped with the RF Receiver and the remote will be having a Transmitter. Every Receiver device will be properly encoded and will be made compatible with its incoming command from transmitter. Lets say there are three doors, each will be equipped with RF receiver, the remote will be having 3 push buttons. On every single push and release of button will send activation and de-activation command to its respective receiver which in result will allow the Socket to get active and allow AC voltage through it and activate the door. I will provide you ONE working prototype, (If unable to deliver, then will show/demonstrate you the live action). Deliverable: 1) Circuit Schematics, 2) PCB Layout and Design 3) BOM (Bill of Material) 4) Working Prototype 5) Proposed wiring and casing 6) Mfg assist. This can also be done through GSM Technology.
