No. The objects I need to detect are non reflective everyday objects i.e. curbs, people, etc (which probably rules out ir). The 10ft requirement is not set in stone, but it needs to detect no less than 7ft. Accuracy is also not a high concern either, I'd be ok with +/-6".
I've been leaning towards an ultrasonic transceiver system. Does anyone have experience with these type of systems? Can anyone recommend circuits and/or devices that will meet these requirements?
