Title: can ir detectors detect heat?
Post by: zackshalac on April 28, 2008, 12:05:00 AM
If i remember correctly, heat is transfered as IR waves, so can you use an IR detector to detect a radiant heat source and move towards it?  Like a photovore, only a heatovore, i was thinking i could build the $50 robot only with IR sensors for a first robot if it would work.

There are specially designed and calibrated IR sensors designed to do just that.  For a standard IR sensor, I do not believe it would work well, if only because most IR sensors are calibrated to a certain frequency range, or pulse.
