They work... but zero documentation

Bought those since the one came with my RexQualis training package was malfunctioning and producing constant readings. Those work perfectly fine. Satisfied with this purchase

I haven't been able to test these yet, but they appear to be well made. The soldering and components all appear to be pretty good and the pins are a good length. I'll update once I have played with them a bit.

So with these ultrasonic sensors they often come requiring 5v. This one operates at 3.3v to 5v and that means you can connect it directly to your ESP chip without having to use resistors to drop the voltage back down to 3.3v.In my case I used an ESP 32 and wired it directly the the 3.3v rail, ground and two GPIOs. While it is not the HC-SR04, I was able to use it just as if it was and wire it without resistors. It worked just fine and there is no risk of burning out the GPIO since it is the standard 3.3 volt.Accuracy wise, it is about what your would expect for this type of sensor. Good for measuring distances to stationary or objects that move consistently closer or further away. I would not recommend this to replace a motion or beam sensor. It would be perfect for measuring a liquid level.
