An e-cigarette has a draw-activated light emitting diode that is activated by an electrical signal which indicates an amount of electrical energy remaining in the power source. When vaping, an air sensor detects inhalation and closes an electrical circuit. A printed circuit board assembly sends an electrical signal to the light emitting diode. In response, the light emitting diode will illuminate in a green color if the power source has an energy level between 51% and 100%; in a yellow color if the power source has an energy level between 11% and 50%; and in a red color if the power source has an energy level equal to or lower than 10%. Such light signals are detected by a user who is thereby informed about the operational state of his e-cigarette.

An electronic cigarette includes an external housing and display unit configured to receive user input and display operational status of the electronic cigarette. The external housing includes an aperture for receiving the display unit. A sensor is integrated into the display unit to detect user characteristics. A controller of the electronic cigarette is configured to retrieve information from the sensor and control the operation of the electronic cigarette.
