Data Acquisition

Thu Feb 12, 2015 5:24 am

Hi, all.

I'm new to the forums, and Pi, and thought I'd asked a resource/use question to get more interested in the hardware.

I work in a lab setting, and utilize a lot of analog signals (0 - 20 mA, 4 - 20 mA, and 0 - 5 VDC), and was wondering if I could use the hardware to log these signals into something like Excel, or some other recommendation that's a common application. I'm sure this is a common thought amongst people, and was hoping someone could point me in the direction of this being done or at least help on how to do this.

The Raspberry Pi does not have any analog to digital converters in it, but they could be added via the GPIO port. This page shows a chip that you can interface to the RPi, and has links to a Python program to read from the ADC: ... i/overview

There are Python libraries to create and manipulate spreadsheets. See this page: ... mit=search
