It's been immersed and functioning for 6 years now. Wow, that's great! I wasn't too lucky with my first attempt (it got wet inside). I'll keep trying, though. By the way, related question: is heat shrink supposed to be waterproof? I mean, if I heat-shrink a tube, can I leave it submerged? > Maybe some static charge in the Vcc lead confused the sensor in the > lightning storm? You know what, I want to get to the bottom of this so I have decided to do nothing now to try to fix the problem I experienced a couple of nights ago when we had lots of rain and thunderstorms. Allow me to explain: Whatever happened a couple of nights ago surely will happen again. When that happens I'll go outside and start with the simple stuff, i.e. grounding Vcc. I am hoping that the problem was caused by either high humidity, or by some weird electric problem caused by not having Vcc grounded. If it is the later I will be able to confirm it by grounding Vcc when the problem is happening. As I said, I have not had a single 85 degree reading since that night, so I have no need to try to fix things right. I'll report back as soon as I know more. By the way, thanks to everybody that have provided useful links and shared their war stories; it's been a very enlightening discussion.
