Thanks Brad,
We were at first thinking of using ultrasonic range finders, but they have the problem of interefering of sounds, which cannot be avoided, unless we change the piezo-electric crystal in them. But that becomes too complicated.
Thats why we are shifting towards Infrared rangefinders. We were looking for those, and came across one IR rangefinder. Its name is GP2Y0A02YK . This one is similar to the one mentioned above (GP2D120), except that it has more range. (20 cm to 150 cm) Around 8" to 59". Its data sheet is provided at

This gives output in the same way - analog output inversely proportional to distance. THe output can be feeded directly to innovationFirst miroprocessor.
If we put two of these sensors, would they interfere with each other ?
Thanks,
Team 612.
