Abstract: Systems and methods for dispensing a liquid fragrance into the air. The system includes a liquid fragrance dispenser. The liquid fragrance dispenser includes a dispenser controller for controlling operation of an atomizer. The dispenser controller, via the sensor subsystem, is configured to detect a value of an external variable of an environment of the liquid fragrance dispensing system. In response to detection of the value of the external variable, the dispenser controller variably controls an output of the liquid fragrance dispenser, for example, the duration of operation of the atomizer, the atomization output of the atomizer, or a user output interface. The system is configured to variably control the output of the dispenser, based on at least one or more of, a value of a detected external variable of the system, data representative of a liquid fragrance cartridge, and the previous atomization output of the atomizer, to achieve a target environmental fragrance condition.
