Hi, i am looking for a moisture resistant HCSR04 ultrasonic sensor to measure water level in a tank, did anyone solve this problem?? Which one of the Futurlec water resistant capsule are ok to change with the original one? US1440 model should be right..?Thanks for any help!!Marco
If you look at DIY methods, you should cover the two cans with a protective material with thickness=1/2 wavelength. Knowing that the frequency of the device is 40kHz, your solution would be a Plexiglas plate of 2.125cm
I habe a IBC tank outside with on top of that a terra cotta plants pot upside down and in the my sensor.That works pretty good for about a year now
Has anyone actually tried to just replace the two senors on the hc sr04 pcb with these waterproof ones?
Oops, after a couple of months of service also my ultrasonic device gave up on me. The little dish inside the speakers came loose and messed everything up. Ordered a waterproof one now, works like a charm
I used the example code
