Wine Cellar Monitoring

I’ve been getting back into wine, and ran across this handy one wire wine cellar monitor. Aside from the usual iButton air temp sensor, they built a simple immersed 18S20 sensor to monitor liquid temperature as well. (I’d toss some sulfites in the water to prevent mold) To keep an eye on air conditions, they used a TAI8540A humidity probe. Looks like just the thing for the geek wine cellar.
