thesis: Keyfob Locator thesis-about an rf device that locates misplace things..

[trebor2787]

Please help us in constructing this idea.. it would be a great help... thank you

General Objective:
   To make a gadget that will enable us to find lost items quickly and accurately. To use also this device that we will make to locate small children and even pets going around the house.

Scope and Delimitation
Pioneering ideas of technology always attempts to bring the extent of its worth. Though the project is assumed to function up to its extents, hindrances that build up into project restrictions are really unavoidable. And that is one valuable reason why various modernizations are continuously concluded. The electronic key Fob Locator is assumed to cover up the following scope and limitations:

•   Multiple buttons on the transmitter in the form of a remote control activate the receivers when pressed. Each receivers work with corresponding buttons on the wireless remote.
•   Each of the receivers has a different color and emits a unique tone and light for easy location in the dark when activated. The alarm is audible enough for you to track important items quickly.
•   The radio frequency (RF) remote control distance range is 40-50 feet.
•   The radio frequency use is 434 MHz.
•   The sound volume range is approximately 90-95 decibels.
•   Each portable receiver has a metal ring and a double stick pads. You can attach each receiver to any object as key chain or you can also stick it to the object.

If your planning to make a prototype it won't probably me the size of a keyfob. Mosly ksi ng gagamitin mong parts eh mga through hole. It is possible to do this. I suggest you use an rf module pra di na kayo mahirapan sa rf part.

kelangan mo lang mag transmit ng signal para sa receiver kung out of range na mag aalarm, yun nga lang kung low batt na receiver di na mag aalarm, kelangan meron ka rin indication sa transmitter kung alin ang nawalay na fob, bale two way ang communication
