MASK APPARATUS AND METHOD FOR CONTROLLING THE SAME

A mask apparatus includes a mask body, a fan module, a seal that defines a breathing space, a pressure sensor coupled to the mask body and configured to sense an air pressure in the breathing space, and a controller coupled to the mask body and configured to control a rotation speed of the fan module based on the air pressure. The controller is configured to determine a breathing cycle based on a maximum pressure value and a minimum pressure value among air pressure values sensed by the pressure sensor, determine a time difference between a maximum time point and a minimum time point, determine an expected time point of inhalation in a subsequent breathing cycle based on the breathing cycle and the time difference, and increase the rotation speed of the fan module based on a current time corresponding to the expected time point of inhalation.
