Variometer is a system that measures atmospheric pressure and using the obtained data, it calculates the altitude above sea level, airspeed, and the rate of climb as well as the rate of descent. Changes in climb and descent rates are signaled as well. The sensor also alerts you if any alarm setting is exceeded.
