Scenario

Home security has always been and continues to be a concern for individuals and families. Most homes nowadays come standard with a security system that is keypad controlled from within the home and is triggered when any of the magnetic contact switches placed on the entrances to the home are broken. What's new is that many connected systems are now emerging integrating cameras and the like as well as online connectivity allowing home security systems to be more comprehensive. The online connectivity enables control through everyday portals, such as phone applications, giving people remote control of their home security, which increases their peace of mind. People can now check on the status of their home from anywhere.

The goal of this demonstration is to emulate such a home security system. The demo system is light activated -- when light levels are low, the system is activated and when light levels are high, the system is deactivated. This was designed with the thought that during the day, when light levels are high, a security system is not needed, but during the evening, a security system would be needed in situations where the lights in your home are turned off, such as when you leave the house or go to sleep. Once the system is activated, it employs pressure sensors at the entrances of the home to detect if someone is trying to enter, and when one of the pressure sensors is triggered, the alarm goes off alerting the homeowners to the intruder. Once the homeowners feel that they are safe, they can deactivate the alarm by resetting the security system (resetting the security system is the only way to turn off the alarm, relieving the pressure on the pressure sensor or turning on the lights will not deactivate the system once the alarm is triggered).
