Some are a little bit faulty.
Best deal you'll find
Ben✓ Verified Purchase•February 28, 2024
Never though I'd say this about a mass-manufactured Chinese product with a per-unit price 4% of name brands, but this is a purchase you will not regret. I normally wouldn't even consider buying this due to the "amazon effect": seeing a definitely-too-good-to-be-true deal, then buying it in a moment of weakness and ending up wasting more money in the end because it works like crap and you have to by another one. This is NOT the case with this product!! All units gave results comparable to name brands (like Ping) -- with a minimum distance less than an inch, and good consistency and accuracy. Arrived far before the estimated shipping date -- only took 6 days. My only concern is that two units had slight dents in the "eyes", but it did not seem to affect their performance at all. Even if half of them were duds I would still be impressed by the price and quality of this product. Can't recommend them enough if your doing a robotics project (like me), and need tons of distance sensors without emptying your wallet.
Still fun to experiment with

Cheap foreign junk, but can't complain too much for the price. Still fun to experiment with.
Very good inexpensive sensor

This model of the HC-SR04 has performed well for an inexpensive sensor. There are a number of these HC-SR04's on the market, with at least 2 different chip layouts (I don't know how else to identify them). The "other layout" model has pretty consistently locked up or burned out when triggered too frequently. A class of 20 beginner students was unable to damage a single one of these. On the side of don't expect too much from an inexpensive sensor, they do have a limited range and work best against hard flat surfaces. Small and/or soft objects produce jumpy data. The data consistency can be improved by using a median filter (if you know how to find or write one). I plan to purchase 20 more for my next class.
nice!

For what it is it's great, it supports the HC-SR04 decently as far as I can see. The only weirdness I saw:
- The datasheet claims you should be able to sense distance by timing the trailing edge of the trigger signal to the rising edge of the echo response, but my testing shows that time is always the same regardless to proximity to an object. Not a big deal, sensing through measuring the duration of echo high works fine.
