Neat
So cute. It measures distance from about 2 inches to over 4 yards. It sends a ping and receives it. From the delay you calculate the speed of sound (divided by 2) to get the distance. Remarkably accurate for such a little toy. Google for program examples.

Only worked at 3V with Node MCU -otherwise OK.
I use this with a nodemcu esp8266. Tried with VCC (5V) as specified, but gave zero readings. But tried at 3V, and works fine. Otherwise, works fine.

super great ultrasonic sensor for Arduino
these work very well. I'm using them to detect water levels to trigger an Arduino to turn on a sump pump. All of them work perfectly.

Simple and easy to use
Very easy to use and functioned great

Very good quality!!
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.

Great ultrasonic sensors for a very reasonable price
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.

Importantísimo las instrucciones
Porque no ponen las instrucciones de cómo usarlos

Perfect
Great value for money and they all worked perfect. Might need to be careful when interfacing with other similar brands of ultra sonic sensors as they might have different pin layouts and functions

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