“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.”

“Very well made piece of kit, works nicely with my RPI 3. Plenty of example code to drive this up on the web for python and c. Got it going with Domoticz. Would recommend that you take three readings and average them for best results.”

“This was perfect for what I needed (collision detection) and was super simple to use and set up. Also looks better than alternatives that I have used (if not a little big).”
