Nice product I used to build a robotic car and it works ok.

The pins have just the right spacing to fit a breadboard or vero prototyping board. Googled up some code, cut'n'paste and it worked with no problems at all.

easy to wire, program and use. great product. I was worried that it would be big and clunky looking but it is surprisingly small and neat

Bought this to bolster son’s set as he works through some Pi worksheets. Works really well. Would recommend

It's accurate and there are comprehensive blogs for use. It is great for close range or large objects - it doesn't like people over a metre or two. I use mine with a Pi0, PIR and an LED array as a parking sensor at the end of the garage.

This sensor worked well with my raspberry pi. It is easy to find out how to use it with just a bit of internet research. I would recommend it for anyone doing a raspberry pi project involving a proximity detector.

Super easy to use, would like a raspberry model with 3,3v out but its easy to fix so really not a prob.
