Waterproof ultrasonic sensor

[Dannnn]

Hi,

Has anyone successfully hooked up a waterproof ultrasonic sensor to their Pi? I'm trying to use one in a slightly humid atmosphere, and the HC-SR04 doesn't seem to like that at all.

The DYP-ME007Y (http://www.suntekstore.co.uk/product-14 ... odule.html) looks like a better option, but Googling finds nobody who's successfully linked one to a Pi.

Any advice gratefully appreciated

Dan

The doc suggests it uses the same interface as the SR04 so the same software and hardware setup should work.

You may also be able to use a car/auto parking sensor (scrap yard) but may also need the controller board.
There are articles online, not sure if they may relate to use with a Pi

thanks, all - I'll give it a go and report back

If you are planning to use UNDERWATER, be aware that descriptions of transducers you're presently looking at as 'waterproof' simply mean they should be OK in a splashy environment.
They are NOT for underwater use.
Sound travels much faster in water. Transducer shape and power & frequency for underwater use are different.
Good idea would to be to look for 'depth sounder transducer' on say eBay

OP is not trying to use it underwater:
