elevator displacement

hey,

i've been given a task to measure elevator displacement with an accelerometer (Olimex mod-mma7260 - mma7260+at91sam7s).

 

i've been reading this application note http://www.freescale.com/files/sensors/doc/app_note/AN3397.pdf regarding implementing positioning algorithms using low end accelerometers. it's been stated several times that these algorithms are useful only for situations where the displacement precision is not extremely critical.

 

what's extremely critical? i want to calculate the displacement to figure out the current floor while the elevator is moving, is it possible to do it with the mma7260 and these algorithms?

 

thanks :smileytongue:
