Wireless Proximity Based Security System
1 Project Overview
The goal of this project is to produce a pair of modules that will communicate wirelessly with each other and be able to detect when one unit exceeds a certain distance from the other unit. You can imagine that these units would be used with one placed in the user's pocket and the other attached to a laptop or device of interest. When the two modules are taken too far from each other both modules would emit some form of signal alerting the user that they are out of proximity. This could be used as a security device or as a lost item finder. Possible improvements could include selectable range, multiple units interacting with each other,and a variety of energy sources could be used.
Similar devices, pertaining to wireless proximity based security, that have been release into the consumer market have utilized an assortment of technologies, including RFID and Bluetooth. These products have also been designed for a variety of specific purposes, such as providing authenticated access to private areas or even portable digital devices. In contrast, this project will focus the device's purpose towards the issue of physical proximity as opposed to authenticating access. This will be achieved by designing a simple-to-use device that can actively detect the distance between the two devices for long periods of time. In addition, the alarm emitted from both devices will be powerful enough to notice in noisy or crowded environments. In the end, this will result in a highly desirable device for consumers concerned about keeping items, or even small children, within secure distances.
* The devices must be very very small.
* The devices must operate for extended periods of time without recharges.
* The devices must be consumer packaged and ready to use.
* Use of the devices must be 'idiot proof'.
* The devices must be able to be heard over moderate noise.
* The alarm of the devices must be very loud.
* The devices need to be very inexpensive.
