I'm working on an essay. I have an idea that I wonder if it is possible to perform. I want to write about it in my essay. It is about how we can prevent children in kindergarten disappears outside that fence. I want to know how I can solve this with eg WiFi, RFID. The child must have a receiver of any kind WIFI or RFID. It will be the transmitter that sends signals to see that the child is still in the area inside the fence. If the child goes outside of the fence it emits an alarm. It should work like a wifi finder. When you then must find the child the alarm will alert faster the closer I get near the Child so i can find him. All functions and methods should be described. It should be clear what they are doing and why they are there. All programming shall be documented like that. The programming will be structured and academic. I'd love to hear your views on the idea. How you will solve it Which programming languages Which komponetner needed How we can improve the time and how it can be made easier. The main thing is that I want quality work
