Problem Statement
The device that I am designing is intended for my housemates. I chose them because they live with me and it is more convenient than to design for a friend that lives elsewhere. A common problem for homeowners regards home security. Sometimes a housemate might forget to lock the door when leaving the house. An Internet of Things device could certainly help remind to lock the door. It would notify them immediately after closing the door to lock it. They could also check whether or not the door is locked remotely. This could definitely reduce instances of unlocked front doors, increasing the home security.
Goal
I want to create a device that will remind homeowners to lock their door after they close it. It will use a reed switch in conjunction with a magnet to sense if the door is closed. It will use a tilt sensor to determine if the door is locked or not. If the door is not locked, an LED will flash rapidly, notifying the homeowner that their door is unlocked. This way, whenever a homeowner leaves their house without locking it, the flashing will get their attention and remind them to lock the door.
