High-Sensitivity 2g USB Accelerometer X2-5

The X2-5 is our newest high sensitivity data logger incorporating the Analog Devices ADXL355 digital sensor. The ADXL355 sensor is a significant improvement over the Kionix KXRB5-2050 sensor used in the previous X2-2 logger. The X2-5 offers 20-bit resolution, 2g/8g range, selectable sample rate up to 2000 Hz, and digital filtering options. The logger operates from an internal 500mAh lithium-polymer rechargeable battery that recharges when connected to a USB port. The X2-5 acts as a USB Mass storage device (like a USB flash drive) when connected to a computer, which provide quick and convenient access to data files. Data is stored as plain text Comma Separated Values format (.csv), ready to be imported into any spreadsheet, word processor, or end user application.

The X2-5 logger is configured using a simple text file called config.txt located on the microSD card. Below is an example:

   
        ; Example X2-5 Config file
        ; 2g range
        gain = low
        ; set to record constantly at 1000Hz
        samplerate = 1000
        deadband = 0
        ; set file length
        samplesperfile = 192000
        ; LEDs on
        statusindicators = normal
        ; make device start upon USB disconnect 
        rebootondisconnects
                  

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:
