Re: Ultrasound vs. IR sensors
I think I should have added, that the sensors will be run from different microcontrollers - 3 to be exact. Two of the UNOs will run two sensors, and then 1 UNO will only run one. I have reasons for this.
Given this situation, that's why I'm asking which has minimal change of interference. I'll be using a target detection range of 1-3 or 1-4 feet.
