data logger

Please note that the X2-5, X16-5, X200-5, X16-1E and B1100 products are not in stock at this time. GCDC can not produce these products due to the supply chain issues of 2022 and the obsolescence of critical semiconductor components. We are in the process of redesigning this product family to use new and improved components. Contact for updated status of our product development efforts. In the meantime, please check our other products, such as the HAM logger, or the MEL logger, or the new IMU-GPS logger.


The X16-5 is a rechargeable version of the X16-1E. The X16-5 uses a digital 3-axis 16g accelerometer, a 500mAh rechargeable lithium-polymer battery, and a convenient push button switch to start and stop data recording. Data is recorded at user selectable rates of up to 400Hz at 16-bit resolution. The X16-5 acts as a USB Mass storage device (like a USB flash drive) when connected to a personal computer. Data is stored as plain text Comma Separated Values (.csv), ready to be imported into any spreadsheet, word processor, or end user application. Read more about our data logger product-line features.

The X16-5 logger is configured using a simple text file called config.txt located on the microSD card. Below is an example:

        ;Example X16-5 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
        ;see X16-5 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:
