perfect for use with Arduino. accurate and easy to use
Used these to make a small radar reversing system.

The first thing you notice is that these are very nicely packaged rather than the typical plastic bags. They also come with both M-F jumper wires and F-F jumper wires. The sensors work as expected and the quality of the PCB looks good. Even the solder joints look great. I would buy these again.

It does what it should, but does not work with 3.3V.

These are not cheap knockoffs. They come in a very high end packaging. They work brilliantly. Any library I’ve tried with them works great. They don’t give erroneous readings like some of the cheap clones do. These are better quality than the Elegoo ones that I purchased before these. By a good bit too. Highly recommend. Will be stocking up on these.

Good distance measure gadgets.Unfortunately, they are not covered or protected in any way, so it’s difficult to use for outdoor purposes, and sometimes it gives bad readings, hence -1 point
