How to interpret Data from Sensors

Postby AAR » Fri Nov 14, 2014 2:35 pm

Hello!

We're doing a project using a BITalino kit and we wish to use Arduino to read data from the sensors individually (we will not be using the attached MCU). My question is, how to we interpret the data read from each of the sensors? Is there some sort of documentation to understand the numbers that will be read and what they represent and how to translate them into meaningful information and so on?

Thanks for your time,

Hi,

In this thread you have the transfer functions that enable you to convert the ADC codes to their correct physical units; these apply for the BITalino MCU block, but may give you a starting point for working with other MCUs as well:

Documentation on how to do things like diagnostics or feature extraction from the signals is something we currently don't have available. Depending on what you intend to do we can refer you to a few resources out there.

Best regards,

What is the number of bits variable when dealing with just using analogRead on an Arduino microcontroller? Also what is the CECG variable?

Hi,

The number of bits by default should be 10 (http://arduino.cc/en/Reference/AnalogReadResolution). If by CECG you mean GECG, it corresponds to the gain of the sensor, which on the current model is 1100.
