high range ir transceiver.

Hello,

I want to design such a circuit that can detect obstacle with range of min. 4 to 5 meter using IR. is it possible?? any suggested components??


thanks..

Sharp IR Rangefinder.

There are lots of infra red devices in industry that operate over a distance, automatic doors being one, their sensors can detect a vehicle or person over 10 meters.
You can make a standard tv infra red receiver work over a good range, 5 meters probably isnt unrealistic.
