I'm trying to find some sensors for distance detection and the ones they use on cars seem like a good fit. I am wanting to detect a solid object within maybe 6' or so. I don't know if doppler or ultrasonic is best - or if there's a different technology that would be better.
Do any of you have any experience with these kinds of sensors? Any direction as to where to look would be appreciated. I have spent some hours on google looking, but really only seem to find industrial pre- packaged sensors. I'm really looking for just the sensor, not the packaging or interface.
Many thanks in advance.
