I built a duel purpose greenhouse. It dries my firewood out like a champ. And I keep figs and tomato plants in there to extend the season.

It's 12 1/2 x 28 feet. I will build another one similar to that next year.


Temperature management in a hoophouse or greenhouse is a big deal for most things that you would want to do in a greenhouse.

I have tried different thermometers that record high and low. They work, but there's no real data logging, etc.


I got excited when I saw a temp logger that they were using in one of the Wofatis.

I hunted them down, and also found a much cheaper version on ebay.

They are $14 shipped. They can record 32,000 data points, at whatever interval you want. I have mine record every ten minutes. It will run for 6 months on one wafer cell.

You have to download some software to use it, but it's free and works pretty much straightforward.


It's starts downloading automatically if you put this in your address box:

It is 60 megs, which kind of surprised me, but hey, it works.

Wow! I have been idly thinking about wanting a recording thermometer, but hadn't seen a solution at a reasonable price point. This looks very promising, thanks for sharing!

Yeah,prior to this one, everything was 50-100 bucks or more.

Oh yeah, it's water resistant as well.

Hey Troy,
So 5 months in how is the temp logger holding up?

A raspberry pi zero (£5), 1 wire adapter (£15, could probably be cheaper) and DS18B20's at £1 each and you can have 60 data loggers logging every minute and storage of data points for years! Pretty graphs, everything!

The cheapo data logger is still working as advertised.

Very interested in the raspberry solution also...


Are there any how-to videos on how to put one of those together?

For geeky types, there is python software and drivers to run it off Linux; drivers good for Mac and Android, also, and run similar products using same chipset.

https://pypi.python.org/pypi/elitech-datareader/0.8.3

You need to use a spreadsheet to play w/the data, so knowing how to write spreadsheet formulas and use graphing commands would be important.
