Hi, I am doing a project in school and need to find a solution for my project.
I have to make a system that allows me to find missing objects in a building. I want to put a tag on the items and with a computer program find out in which room the items is instead of looking into all the rooms for the item. Think a building like the picture below with lots of rooms. I want to find out a method for finding a missing object. If the item is in room 113 I want to see in my program that the item I am looking for is in room 113.
Can you give me some solution on how I can solve the problem? And what method or technology I should use? I have an Arduino with XBee module I can use.
