As part of a longterm study on stress and physical fatigue, am interested in combining the 3 axis accelerometer (+/- 15G?) breakout board output to the data logging module to capture both 3 axis forces plus timestamp for each read. Would like both variable sampling rates (15sec - 5 minute) and threshold trigger level recording. Will need to capture data over a 1-2 week period, will 2GB memory cards work? Suggestions on which boards to purchase and if there’s already a SFE Widget combination available?
