Weatherproofing DS18B20

[CantSpell]

What is a good way to weatherproof one of these sensors (and cable entry?)

I hope to be able to poke a weathreproofed sensor through narrow slots in soffit to measure outdoor temperature.  So it will be sheltered, but still vulerable to damp, ice, etc.

I'm thinking of somehow using heatshrink sleeve, tucking end in itself to make a "DS18B20 condom".

Alternatively, has anyone discovered a cheap source of one-wire outdoor thermometers?

I use microbore copper pipe and thermal compound but thermal epoxy might be a good choice also

I used a drinking straw, heat shrink sleeve and epoxy. The sensor is in a sheltered position (tucked in between some ivy), been outside for about 6 months and still working OK (currently showing -2.5C brrrrr).

just spray some conformal coating on it?

I used Liquid Electrical Tape

The liquid electrical tape looks a very useful product. Does it have a shelf-life? I've purchased useful products before (eg sikaflex) to find that after a couple of years on-the-shelf, it sets hard and is useless.

Ivan, your shelf must be too hot :-) I just used the second half of a tube of sikaflex I originally opened in June 2003. It is now very stiff but still just about OK to use once I'd warmed the tube in front of a heater (then wrapped in bubble wrap to use in the approx +2 outside a couple of weekends back). I guess I'll see if it's actually still flexible enough to be waterproof soon enough (solar roof vent on van) (carpark barrier got the old one). Bl**dy good stuff sikaflex.
