Waterproof ultrasonic sensor

hello all,

Has anybody managed to use the HC-SR04 node with a different sensor? I’ve got a waterproof one and was hoping to just adjust the node a bit to get it working, but no luck as of yet. I cant find much of a data sheet but it looks like a PWM version clone of A02YYUW. With my amateur status I can spot the following difference, HC-SR04 gives a refresh rate of 40Khz, the clone says a response time of 100ms.
I’m not sure it can be done, but thought id ask the collective if someone has managed to do it.
and would care to share their experience.

Thanks for reading!
