The problem that my partner Alana and I are trying to solve is when unwanted people or pets enter your room when you don’t want them to. We are planning to use some sort of sensor (most likely a motion sensor) that will detect when someone enters the room and will send a notification to your phone. We came up with this idea, as we thought of our family members and others who we don’t always want in our rooms. However, this idea may also work if you have small children or pets at home that are unwanted in spaces like the laundry room or the kitchen.
