I have been searching Google for about 3 hours now and I'm not getting anywhere so I though I might ask if anyone knows of any super small distance sensor. It needs to be about 10mm X 5mm or smaller. Furthermore I would really prefer it use less than 100mA and have a range of at least 6 inches. I have found sharps SMD IR proximity sensor but it hogs a lot of power and it too big. I was kind of leaning in the direction of ultrasonic since it uses less power for having a longer range, but I can use either or. Price is not an issue and if i come to the last straw i will probably end up buying some smd transducers and make my own. Thanks in advance and I will keep searching Google!
