I'm terrible when it comes to technology, but I think there may be something similar to what I'm looking for I just don't know what it's called.
I'm looking for some type of sensor that has two parts, both parts with the capability to detect the proximity to a its counterpart and possibly make a noise or something when they come within range of each other. Does this have a name? Or am I totally losing my mind here?
