I don't really understand much of what you guys are talking about but I am really interested. I am currently debating between a BCS and a brewtroller and like where this discussion is heading.

Here's a shot of the gauges on a client machine. The top 4 show the temp in F of my 4 sensors. The row below that shows the same sensors in C.

Finally a use for my Pi. I am in the process of switching to an electric setup. Due to limited space this will just be a single kettle batch sparge setup in the basement. I think this might be the solution I have been looking for the ability to set some parameters and monitor remotely and come back when I have hit targets in the brew process.

I have determined that I will need a relay block either USB or GPIO to control the SSRs to drive the element and random pumps ect...

What I am not sure about is the temperature sensors.What is the general consensus for connecting the temperature sensors USB or GPIO?

Here are some ideas of parts I am considering

USB relay and input controller

This is exactly what I had in mind for the Pi's. I have gone through a couple of the 'wireless' digital thermometers and the range on them is only good for about 10 feet or so. To buy a true 'wifi' digital thermometer can cost a bundle! It would be nice to figure out a way to use the Pi's for this! Subscribed.

Found something that may help get rid of the old sightglasses: Ultrasonic sensor on ebay

Seems like it would be pretty easy to read levels in all three vessels for pretty cheap. You'd have to give up one IO pin per sensor. This would be one more step toward incorporating automated valves and having a end to end automated system

Github is a good place that would let everyone see/contribute to the coding project easily. I think it'd be worth starting up a github project so that information can be put into one place.

That being said, there is a lot of knowledge floating around this thread. Thanks for putting in the hard work!
