Ultrasound Distance Module Overview

Ultrasound Distance Module Overview

I just thought about implemententing a small ESPhome based ultrasound water level module, when I realized, that I have none of my modules left. Maybe I gave the last one away to a friend of mine, so there was no chance to look-up which one I had… Nothing easier than ordering a bunch of new ones, but this task got a little more complicated, since the variants of cheap US distance modules is just overwhelming: HY-SRF04, HY-SRF05, HC-SR04 (5V,2H), HC-SR04 (5V, 4H), HC-SR04 (3-5V, 4H), HC-SR04+ (3-5.5V, 4H), US-100, US-015, US-016, US-026, UNS-016, UNS-100, IOE-SR05, RCWL-1601. So I decided to collect some of the infos at a central place…

As you can see, for some modules, you will even not find data… So better stick with the known ones.

To integrate it into ESPhome, most of them easily can be used, maybe with minor adjustments.

If you have additional datasheets available and also links to shops that can provide them, feel free to send it over to me.

I ordered already a bunch of it and as soon as my modules arrive, I’ll write some follow up here and I’ll ylso provide the shopping links, as when I’m satisfied with my order.

Happy tindering!
