This is part of my Arduino Controlled PC Liquid Cooling Information Center I have been working on and I thought I would share it here since there have been a few threads on arduino.cc and seeedstudio.com on how to read water flow rate in liters per hour using the Water Flow Sensor found in the Seeed Studio Depo. It uses a simple rotating wheel that pulses a hall effect sensor. By reading these pulses and implementing a little math, we can read the liquids flow rate accurate to within 3%. The threads are simple G1/2 so finding barbed ends will not be that hard. I found some at Lowes for $1.89 each.

Need a flexable Arduino? Seeed Studio has that!

For a couple of months now we have been reading snippets of information on Seeed Studio's newest Arduino variant. It promised to be the smallest ever and be flexible. How could it be flexible you ask? That’s quite simple. Seeed Studio designed the board on a flexible film similar to ribbon cable found in electronic devices that use it to connect a display to the PCB. Seeed Studio says that it is “cutable, scaleable, and chainable.” They are in the process of creating a few prototypes and if you leave a detailed comment on their blog post, on how you would use it, they might send you one to test with.

Update + Development Setup Pics
Over the last few weeks I have had several emails asking what my development setup looks like for this project. Today I am going post a small update and a few photos of my development setup. First I would like to give a big shout out to all the guys over at Seeed Studio. Their Seeeduino has played a big role in this project and now we will be using their Seeeduino Mega along with 2 of their Water Flow Sensors to complete the project. Stop by their online store and check them out for all of your open source project needs. Keep reading after the jump for more ACLCIC excitement.
Part 2: Reading Fan / Water Pump RPM
In part one I covered how to connect two temperature sensors and the LCD to our Aruino. In this installment I am going to show you how to read the RPM of the water pump. The Arduino Controlled PC Watercooling Information Display will display the water pumps RPM on one screen so I had to figure out how to read the RPM from the data output by a Hall effect sensor...more after the jump...
Part 1: Reading and Displaying Temperature
This is a side project for my COD MW2 case mod found here. The plan is to build a water pump cover that has a 16x2 or 20x4 LCD that will display several parameters about the water cooling loop including: 2 temperature locations, Pump RPM liquid flow rate and possibly even an audio alarm in the event of pump / flow failure. In this installment I will show you how to read the temperature from 2 10k thermsistor based temperature probes and display them on a 16x2 parallel LCD display... More after the Jump...
Our first order from Seeed Studio arrived today !!!! YAY!

Our first order from Seeed Studio came in today. It took about 12 days to arrive from China but it was well worth the wait. A few weeks back I commented in a tweet that I was considering using a Rainbowduino from Seeed Studio in my Call of Duty Modern Warfare 2 case mod. It would be used to control the RGB LED accent lighting. Fan at Seeed Studio commented back saying that he was keeping... more after the jump
