A device for controlling electrical power supply in response to air pressure measurement includes an airflow path, a chamber having an aperture, a liquid flow restrictor configured to inhibit ingressof liquid into the chamber via the aperture, a pressure sensor located in the chamber and operable to detect, in the presence of the liquid flow restrictor, air pressure changes caused by air flow inthe airflow path, and a circuit for converting air pressure changes detected by the pressure sensor to control signals for controlling output of power from a battery. 一种用于响应于气压测量来控制供电的装置，包括：空气流路径；腔室，具有孔口；液体流限制器，被构造为抑制液体经由孔口进入腔室；压力传感器，位于腔室中并能操作以在存在液体流限制器的情况下检测由空气流路径中的空气流导致的气压变化；以及电路，该电路用于将由压力传感器检测到的气压变化转换成控制信号以用于控制电池的电力输出。
