Big wind storm blew down my fence. Unit was on fence and ended up in the pool. Changed batteries but sensor doesn’t work. What can I do?

There is a high likelihood that it is dead, but don't write it off yet.


Remove the batteries and let it dry completely. Maybe even a couple of days. Then try to bring it up again. Much of the electronics has a conformal coating on it that may help it survive. The T&H sensor is most vulnerable, as it is literally open to the environment. That might be replaceable if it is the only casualty.

If you measure the current draw from the batteries, you may get a clue as to the health of the 5n1. A properly functioning device will idle at about 20 microamps +/- . Every 18 seconds the current will shoot up into the tens of milliamps as it goes through a compute and transmit cycle. The burst is too brief to properly register on a DMM, but you will know that it is happening. Big deviation from that behavior confirms bad news.

The Humidity sensor will have suffered.
Total replacement is suggested if the 5in1 was drenched in anything but distilled water (which pool water is not even close).

Although distilled water would make for much healthier swimming pool water :)
