Abstract
An atmospheric pressure measuring apparatus allows a transmitter to transmit an acoustic wave for measurement of the atmospheric pressure. Air propagates the acoustic wave. A receiver receives the acoustic wave. Since the intensity of the acoustic wave changes to follow the variation of the atmospheric pressure, the atmospheric pressure can be measured based on the intensity of the acoustic wave received at the receiver. The atmospheric pressure is in this manner measured with such a simplified structure.
