The invention relates to an electronic cigarette equipped with double air pressure sensors and a control method thereof. Herein, the vaporizer of the electronic cigarette comprises a mouthpiece, a vaporizing tube, a liquid reservoir disposed in the vaporizing tube, a heating member and a vaporization passage, wherein a heating resistor is disposed in the heating member, and a battery, a control circuit board and an intake passage are disposed in the battery stick. The control circuit board is arranged with a micro-controlled switch, a microcontroller and a power adjustment module. Double air pressure sensors are disposed in the intake passage, including a switching air pressure sensor for detecting the suction force and determine whether the suction force reaches a switching value to switch on or off the micro-controlled switch, and a digital air pressure sensor for detecting the magnitude of the suction force during the working of the heating resistor to allow controlling of the amount of the vapor. The electronic cigarette comprising both the switching air pressure sensor and the digital air pressure sensor has advantages as follows. It not only can adjust the amount of vapor according to suction force, but also can based on the suction force automatically enter activate state or sleep state to save energy, whereby battery life and service life can be increased.
