It would seem that ultrasonics have to transmit the sound that is to be reflected back - infrared might just "see" the a warmer object without having to transmit.

why don't you try both approach and see what suits you. i believe each set up has its own way of placement, so neither can you say the other one is better than the other one or vice versa. also each one has its own limitations. :wink:
The main problem: light speed is 300000km/sec, sound speed only 330m/sec, so the response time of reflected beam enough long for simply PIC or normal CPU for calculating of distance when You use ultrasonic method....
