Altimeters are of two types: pressure and radio. Pressure based altimeters depend upon air pressure. They tend to be used in light aircraft, and you have to keep fiddling with them due to high and low pressure systems (see your weather report). They will lie to you about your altitude if you don't keep adjusting them. Radio altimeters simply beam a radio wave down and then capture the reflected return. The time it takes from transmission to return can mathematically tell you your height above the surface.
