Im looking for a altitude/height/barometric sensor that I can use for height measurments in the range 0-2 meters (from the floor (0), and to the height of a person (~2 meter)).
I like to connect this sensor to an AVR for an easy to use height sensor. laser, IR and ultrasonic will not do in this particular case, cause I will not like to be dependent on reflecting surfuses and similar. I would find it neat to be able to close it all up in a box with just a display outside.
I havce looked around on barometric sensors, that seems promissing, however, I can not figure out if
are they sensitive enought (a resolution of about 5cm would be ok, but not more)?
Relative height is ok, intending that I can always 'set' the 0-height at the start, then lifting my sensor up to the height I like to measure (a person, a shelf, a table).
Will a barometric sonsor do this, or shall I look into other sensors?
I like a low-cost sensor for this project, since its a 'for fun' project. IDeas of sensors, I have searched the web without good results....
