Rishi dont be lazy and please please read up on sensors, first in your text book related to your course. If you dont find it there, read about it on the internet. Here is an article on "Sensors" from Wiki!!!

Sensor - Wikipedia, the free encyclopedia

Hey, rishi. Thanx for showing interest in my post.
The dude (chandu) needs a sensor for distance of 3 to 30 feet. As per my knowledge only 2 sensors r available for big distances. They r laser & RF. Laser is difficult to allign & as he is a mech engg student, i think he needed to sense some displacement. So the answer.
Plz inform any correction.
Thanx.x
