good, but my cat hates them
These are quite good. Do need the 5v power, so careful when powering with an ESP32 that takes 3.3v usually. You will need to take that into account.These are quite well documented online for how to use, and the accuracy is not strictly within 3mm but it's definitely in the good enough range for most applications.Unfortunately, however, I have had to stop using mine. Ultrasonic for humans, yes, but the 40khz wave is well within the range of hearing for my cat, who hates it.

Terrific sensors for Pi robot hobbyists
These are perfect for my Pi based robotic projects (they're kind of like a sonar system for robots).The quality appears top notch and considering the pack includes some little perspex mounting brackets and nuts'n'bolts, represents good value for money too. Although there's no instructions included, if you are looking to buy these then you obviously know what you are doing and finding documentation online will be second nature to you. Recommended.
