Waterproof Ultrasonic sensors

I have bought a number of ultrasonic sensors from you (SEN0153, SEN001, SEN0207 and SEN0208).

Only the SEN0208 seems to work for any length of time in a humid (but not in water) environment - even though I was told on the product page that the low power SEN0153 was waterproof. Can you please reconfirm if this is the case as I have a few failures of SEN0153 and just ordered two more which I would like to cancel and switch to the more reliable SEN0208.

Please advise - very disappointed so far with reliability, both SEN0207's I received were not working.

2017-10-17 06:04:03 The SEN0153 has no "probe", the Ultrasonic transducer is attached to the PCB and I sealed around the sensor so that was all that was exposed to the humidity. That still fails, so the comment that this sensor is waterproof on the product page is misleading and I believe incorrect. userHeadPic scott
