ph level

[needyourhelp]

Hi:)

I am a student who learns the LabVIEW 2010.
Using LabVIEW program, I'd like to measure the pH levels and grid graph.
Therefore, I'd like to buy pH meter which can be connected with computer for transmitting the data.
However, I am a beginner so I barely know what I have to buy and prepare.
Please,help me which stuff I have to buy.

Option1 : Acquire analogue Voltage

I think I like this one... http://dfrobot.com/wiki/index.php/PH_meter(SKU:_SEN0161)

If you can do it with Arduino, you can do it with LabView to! 🙂

Use a DAQ to acquire the analog output of the pH meter. Or if you have more money to spend, option 2,

Option2: Serial Read

You do not need any additional hardware and can use a VISA-Read example from labview to get your ph Valeus.

there must be 100 other examples, I just googled above two... you will have to choose the probe you like most!

And a link to a previous post about Ph Meter... I'm sure there are others

+ if you have a student license, you should start with LV2014 🙂

Good Luck!
