An electronic cigarette includes: an atomizer, defining a liquid storage chamber formed therein; a heating element, communicated with the liquid storage chamber; a power supply, configured for supplying power; a controlling unit, one end of the controlling unit electrically connected with the power supply, the other end thereof electrically connected with the heating element; and a capacitive transducer electrically connected with the controlling unit. Two electrodes are disposed inside the liquid storage chamber for determining an amount of the tobacco liquid in the liquid storage chamber. A using method includes: conducting the electricity and controlling the heating element to atomize the tobacco liquid in the liquid storage chamber; detecting an amount of the tobacco liquid in the liquid storage chamber via the capacitive transducer. When the detected amount of the tobacco liquid reaches a preset value, the electronic cigarette emits alert information or cuts off the electricity.
