Cheap, easy to use, relatively accurate.
5 Stars
Cheap, easy to use, relatively accurate.
The only thing to keep in mind is to give it a bit of time to rest between pings. Gets wildly inaccurate if you run it in a tight loop. Probably because of echoes from the preceding ping. But this is not even a little surprising. Also, if you're running the MCU on 3.3v, this thing wants 5v. Otherwise, it's a rock star. Okay, a "B-list" rock star, but hey - for a few bucks, whaddya want? :-)

1.0 out of 5 stars These don't or barely work.

I used three of these for a self-driving car. One worked. I swapped out the duds for two others in the pack. Also duds. Even the one I got to work isn't consistent. They all return 0 in serial console.

Avoid this supplier, they're too cheaply made to be any good. Spend 10$ extra for the HY-SRF05/HC-SR05 instead for your ultrasonic needs.

3.0 out of 5 stars Bad firmware. Avoid this supplier.

These sensors will work fine for about 2 min before they hang and return 0 in the Serial Monitor (if using with Arduino). Needed to cycle power each time to get them working again. Tried using the timeout function in pulseIn (again, if using Arduino) to no avail. Possibly a bad transducer.

Made in China; save yourself the stress and effort and buy the real thing, even if it's pricier. It'll probably work better than this product.

[EDIT]: Found that power supply was an issue. Still sometimes reads 0 for no reason, but less frequently.
