Default Arduino Based Beer Monitor System

Reading through the DIY forum has gotten me thinking about a project I'd like to undertake, an arduino based solution for monitoring things like temperature, power usage, and keg volumes. Here's what I have so far:


If anyone has any ideas, comments, questions etc let me know I'll be sharing the code and schematics when I am finished.

Very cool! Thanks for sharing. Just got my first Arduino last week, and didn't even think about using it for brewing.

How will you clean the flow meter?

Cheers and happy coding.

Since the sensor is separate from the fluild, I figured I would sanitize the sensors by flowing star san through the lines.

Parts from Grainger came in today.

I have had quite a hard time finding an 1/2" female screw to 3/16" barb adapter. I compromised with a 1/2" female screw to 1/4" barb, then a 1/4" barb to a 3/16" barb, as pictured below:


1/2" -> 1/4" barb: http://www.grainger.com/Grainger/THOGUS-Female-Adapter-3XVT2
1/4" barb -> 3/16" barb: http://www.grainger.com/Grainger/THOGUS-Reducing-Coupling-1VRW4

(they come in packs of 10).

I'll be going out to get some tubing tonight and to test out the flow meter performance.

What flow meters did you choose?

RGB LCD Shield: https://www.adafruit.com/products/714
Flow Sensor: https://www.adafruit.com/products/828
Temp Sensor: https://www.adafruit.com/products/381
Proto Shield: https://www.adafruit.com/products/196

The proto shield sits in between the LCD and the arduino, allowing me access to all of the pins (the lcd only uses i2c so all the others are game). It's still in the mail. I'm going to the hardware store tomorrow to get some tubing etc and get the flow meter tested.

Is the flow sensor food safe? Couldn't find info on the website.

I found some specific details about it here http://www.seeedstudio.com/wiki/index.php?title=G1/2_Water_Flow_sensor

Everything looks fine except the ferrite.
