    I am currently working on a project in which I would like some light to light up on a device when it is X amount of distance away from lets say a transmitter. This range is only going to be between 100-1000ft and the transmitter will most likely be indoors. I was thinking of adding wifi to the device to pick up the signal but it looks now like that can not be the case.
    I was wondering what people's ideas were as to how I can add this sort of functionality to my project. This device is trying to be as light weight and power friendly as possible as it is powered by small batteries. I have been looking around and can not find a good answer on how to do this.
    Please include any sort of additional hardware or IC's that would be necessary.
    Thank You so much ahead of time and if you have any more questions, please feel free to ask. I know this is generic but I am trying to keep this project under wraps for now.

    How accurately do you want to know X?

    A wi-fi sniffer is cheap and comes close to what you have described, but it's not a range finder.

    is it line of sight between the transmitter and receiver?
