DOOR ALARM SYSTEM

Our team has chosen to work on a project that would assist in the day to day lives of those working at the South Asian Autism Awareness Center (SAAAC). The SAAAC offers programs and serve entrances and exits at all times a wireless real time controlled system was the ideal method of solving the problem. From this our team chose to implement a smartphone controlled door locking system. The door locks can be controlled through a simple user interface via a smartphone application that would unlock and lock the doors in real time whenever the client sees fit. In the event of power and or connection loss the locks can be controlled through a manual override only accessible to staff. While similar products do exist on the market many are extremely expensive, require additional modules for functionality, and have known usability issues. Our goal is to provide a device that is a fraction of the cost, self contained, and able to operate with little to no issues.
