The plotdat
Use the AAUIMUKIT to collect data from an experiment.
a trip in the lift from top floor to cellar
Convert data to engineering units
See if you can estimate the altitude between top and botom of journey
Maybe apply filtering
more on this later
The real plot
We have carried out a fall experiment
Samplig time 10 msec (100Hz)
Data is in the folder named as dishfall10msec.txt
Src folder list: here
The exercise
Try to use accelerometers and pressure sensors to altitude determination.
Calculate norm for the 3 axis acceleration
Is it freefall or is there a slightly resistance due to air friction
The Arduino code src/sketchbook/mpu606xbmp285rob3no3/mpu606xbmp285rob3no3.ino
A precollected data set is available
See forsoeg2a.html for the elevator experiment.
