Voltmeter Data Logging

03/31/2014 5:17 PM

Attaching a data logging system to a voltmeter:

Produino ST Master Chip 0.56" LED DC 3-Digital Display Digital Voltmeter- Black (DC 0~100V)

Goal: I want to save the data from the voltmeter over time with a ± 10Hz sampling rate, logging this on a SD card or UBS stick, making it able to read the data on a PC.

Question: In what possible ways can I achieve this? Can I maybe use the arduino for this and if so, can anyone sum up the parts I need and steps I need to take?

Thanks in advance

The Arduino is capable of everything without the inclusion of the Produino.

The analog input goes to the Arduino and is processed by it.

It's all done in software; and the output to the display comes from the Arduino.

The prototyping boards allow for the progaramming and SD interfaces you need.

www.arduino.cc

Will provide all the info you need.

If you're doing this for educational purposes then follow the above. If you're doing this because you need to collect the data, do this, it's cheaper and requires no effort.

I have two of those and can confirm that they work well.

I've used the earlier versions of this low cost data acquisition module as well as one of the older high-end units. They all worked well for our applications.
