I am trying to make a IR distance sensor. I have seen this online. My goal however is to see the distance between a IR transmitter and my IR sensor. In the example above he uses the IR led's ambient light and timing to track the distance. Is there a way to find the distance between lets say a IR remote and a sensor? It would only have to be accurate to about 1 meter. I am also open to other ideas of accurately tracking distance between two objects weither that be bluetooth/ir/ultrasonic

  • $\begingroup$ If you don't have an accurate way of knowing what the start time for the distance measurement is then you won't be able to do this. Distance is speed*time so if you don't know the time you are stuffed. $\endgroup$ – TechAUmNu Aug 8 '16 at 8:39

I also agree that the stereoscopic technique will probably give you a better result. To implement this you have 2 options, either 1 led and 2 cameras or (I think the better option) 2 leds and 1 camera (which is the technique they used with the wiimote). You can see the second approach here

You would be better off setting up something that uses a stereoscopic technique. Think of something like this. Another similar product is the Leap Motion.

In your case, you could probably get away with just two IR sensors, and one emitter, because of your setup. However, "accurate to 1 meter" is not realistic for most kinds of IR rigs. They usually only function within 0.5 meters, but can be pretty accurate when tracking something inside of their range.
