There is a lot of good information here that I am already digging through but I wanted to get some ideas from what others have done. We have a very creative community here and there's no need in redesigning something someone more skilled than I has put care into.

Just a quick idea of my goals. I am looking to increase my data logging of my process. I'm particularly interested in seeing the differences of fermentation while using spunding valves and keg conditioning. Fermentation is done in a conical, 2 sankes with a thermowell (will be added to the chamber), cornies, and a cheapo steel ported fermenter. What I would like to do is keep track of as much information as I can about each fermentation (say 4 batches to keep up on at any given time).

Having a timeline of the brewday will help with consistency practices and fermentation data will be important while I test cellaring efficiency.

Temperature is great and density included is even better. A means to monitoring pressure too, and I'd just be over the moon. Pressure I can easily read and set in a spreadsheet but I figured I'd throw it out there.

So I think if I understand correctly I need to build/buy a brewpi of sorts and arduino chip? Is there newer tech I should be looking at? When I looked this up briefly 18 months back the brewpi site was the same and makes me wary. If there are 4 ports to a brewpi does that mean each port is for one temp probe or can speak to a tilt-like device or perhaps open a solenoid valve for a chiller system?

Any ideas on how to get the tilt into a housing that isn't plastic. I don't need it to survive a boil but I'd like to bake the housing wrapped in foil and assemble chip just before use. I brew with yeast and bacteria that can become pernicious without aggressive sanitation.

Are there other choices?

Thanks again folks in advance!
 
As a start I would look at the Brewometer/Tilt. It posts updates of temp and SG to google spreadsheets so you can get a history from the first hour until the fermentation is done. I'm not a programmer so I can't help on the pressure thing.

Here's the Tilt link: http://tilthydrometer.com/

There's a fairly long thread about this on HBT.

I have two and am happy with their performance. No affiliation.

So my concern has been sanitation with the poly they use. It's great that it handles sanitizers well but scratches in plastic are condos for bacteria and small yeast which I work a lot with. I'm glad to hear other people are happy with theirs, I may well get one myself for ales. Thanks for your input friend.

Seems like there are still battery life issues...

Cheers!

Funny you mention that. I asked a hardware guy about wireless hydrometer options to build one and he said wireless is not there yet for the reason you mentioned. Either the connectivity is spotty or you overbuild as a fix and you run into the low ceiling of battery technology.

He said he would be interested in speaking with me about creating a wired option but I don't know how something like that would work.. The tilt depends on, well, the tilt angle of the unit but something tethered won't work the same way. I will keep people posted on what this person has to say.
 
brewpi is certainly great for recording temps. it even stores the data onbox and you can export it. i have used it for years for this and i can go back and look at any brew and see how i had it set and what the actual temperature readings where of both my beer and the chamber.

no reason you couldn't modify brewpi (it is opensource) to handle other sensors. of course you would need to know how to code :) there are lots of arduino options but i have not seen anyone successfully doing gravity or pressure with it. sparkfun is a great site for arduino stuff.

brewpi also has a great forum where you could search to see what contributors have been up to.

Thanks a bunch! You know Vernier was on my radar for a while now since I used them for a lab a while back. I had no idea it can be read with arduino. So that means it can be integrated into the BrewPi? I still don't understand how the parameters for each sensor are coordinated. The folk at the BrewPi forum have been responsive and great. But the trouble is the community seems to be starting from a place of knowledge that I am not at.

The pH would be useful data, particularly for bretts, mixed pitches, and kettle sours. Pressure is perfect for the spunding setup, love it!

Density is the final challenge, maybe I'll need to pick up the Tilt and experiment with housing it in another material. Another project for another time...
