X16-1D

X16-1D

The X16-1D is a hardware update to the X16-1C. Priced at only $89, the X16-1D is a very economical data logger packed with exceptional features. The X16-1D implements a digital 3-axis 16g accelerometer with user selectable sample rates up to 400Hz. This simple device stores precisely timed acceleration data on a microSD flash card. Just plug it into a PC, and the X16-1D mounts as a USB Mass Storage Device similar to a USB flash drive. Data is stored in plain text Comma Separated Values (.csv) files, ready to be imported into any spreadsheet, word processor, or end user application. The X16-1D options are easily set up using a simple text based configuration file. The X16-1D operates from a replaceable AA type alkaline battery (ANSI type 15A or IEC type LR6).

The X16-1D logger is configured using a simple text file called config.txt located on the microSD card. Below is an example:

   
        ;Example X16-1D config file
        ;set sample rate
        ;available rates 12, 25, 50, 100, 200, 400
        samplerate = 100
        ;record constantly
        deadband = 0
        deadbandtimeout = 0
        ;set file size to 15 minutes of data
        samplesperfile = 90000
        ;set status indicator brightness
        statusindicators = high
        ;rebootOnDisconnect
        ;see X16-1D user manual for other config options
                  

Data is stored to simple text formatted .csv type files, which are easily imported into any spreadsheet or analysis software (Matlab, Octave, R, etc). Below is a example data file:
