Hello everyone.
i would like to know if there any sensor that can provide details of an object, specific distance from ground.
lets say i have an object that is in another room and my friend moving it up from the floor, and i want to know how far from the floor it is.

Hi... there are a number of ultrasonic sensors on the market.

Google "arduino ultrasonic" and you'll get more hits than you will be interested in reading  smiley-razz

There are YouTubes to watch, and code libraries to implement it all.

Why not?

You could have the sensor on the floor, pointing up, reflected from the underside of the object as it's lifted.

There are barometric pressure sensors that can be used as altimeters that have resolution of 10's of cm so it would tell you when the box was lifted, when compared to a baro sensor that stays at the same height so you can avoid false alarms due to changing atmospherics.  You could also look at rapid changes that would indicate lifting of the object and not changing atmospheric changes.
