HC-SR04 Ultrasonic Module Distance Sensor fit for Arduino UNO MEGA Nano Robot XBee ZigBee (Pack of 5 pcs)

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

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.

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.

What i like is items like this are available for a good price. fun to mess with.

I mainly got these ultasonic sensors to play with and learn more about electronics. I have been able to hook them up to my Arduino for testing purposes and they work as expected. The range and accuracy is inline with the specs (~.5 inches to 15+ feet). I hope to add them to little autonomous cars that have light and proximity sensors.Even though my experience is somewhat limited, these have been good for my education purpose so far. I happy with these and would recommend to others looking for a set of ultrasonic sensors.
