What I need:
I have a little project where I need to create a device or system to identify an object within a 20-50ft radius. For example, an object is marked and as you get close to it, you have a receiver in hand that beeps or indicates how close you are to the marked object. Here are some "ideas" I have (I am not sure how viable they are though), and I am open for other suggestions on how to make this work:
For conversational purposes, let's say the object we want to mark or find is a set of keys.
Idea 1: You mark the keys with a special marker. The ink in the marker is magnetic or composed of some other substance that can send a signal to a handheld receiver which beeps or has a blip on a screen indicating the location of the keys.
Idea 2: Utilize a thermal imaging camera to find the keys. The keys would obviously have to be covered in a substance (clear and odorless compound), that either emits a cold or warm image that can be easily identified by a thermal camera.
I would like to note that I am not an engineer or scientist, and do not know if these ideas are practical. However, I am looking to make this project work somehow, so I am open for suggestions.
