Quick question about the DS1621 thermometer. If I'm measuring outside temperature, how am I supposed to protect this IC from the weather?
Thanks,

Electric Rain said:Hey, thanks Nigel! I wasn't even thinking of that! That's just the kind of answer I was looking for.
I'm having a bit of a problem though, I can't find any boxes small enough to fit the IC without to much extra space, that are cheap enough and vented. It's just going to be the IC in a socket with a 4-pin RJ-11 jack, in the box. So what should I do about that? Do you have any suggestions?
Thanks,
Rain
Edit: Should I create my own vents on a box that will be small enough? If so, how should I create the vents? :?

using 1/2" cpvc (the smallest yellow stuff), I'd take a cap and crazy glue the thermometer to the inside of it, with leads attached to the rj11 jack.
then fit the cap over a piece of pipe, maybe 3/4" long, depending on the size of you rj11 jack, wrap it with electrical tape so it forms a solid "plug" in the open end of the pipe.
for ventialtion, using a drill press or free-hand with a vise, drill a few holes into the pipe on at least a 45° angle so rain can't easily make it in.
quick coat of white spray paint, and you've got an enclosure that cost around 50 cents

Electric Rain said:Yeah, me too. I had to have a phone line running along the side of my house to get a line to my computer modem. No cords were long enough. Even one I made. So I had to use the standard RJ-11 couplers for it. And no matter how much duct tape and electric tape I put on it, the thing was still rusting. :lol:

You need to use the right tool for the job, neither electrical tape or duct tape are designed for water proofing.
What you need is "self amalgamating tape", it's not sticky, but you stretch it tight around the joint and it bonds to itself - creating a single piece of rubber around the joint. Because it's under tension (due to the stretching) it makes a really nice watertight seal on the wires.
It's commonly used for sealing satellite dish connections - I've replaced 10 year old LNB's, cutting the tape off with a knife, and it's absolutely brand new underneath.
