The present invention relates to a perfume dispensing device, the device being electronically controlled and the actuation of perfume spraying being performed via an actuator (12) located on or under a device housing (1). All components of the device are located on or in the housing (1), wherein the housing also accommodates a control circuit (10) for controlling the device, which may optionally include a system (13) for wireless communication with a smart device (14) having a dedicated application uploaded, through which the user sets the desired parameters. The device may include several storage containers (2), which allows the user to select the desired perfume or to personalise the perfume via a dedicated application. The actuator is actuated by pressing or touching the actuator (12) or via an external device.

One variation of a method includes, during a calibration period: triggering collection of an initial bioaerosol sample by an air sampler located in an environment; and triggering dispensation of a tracer test load by a dispenser located in the environment; accessing a detected barcode level of a barcode detected in the initial bioaerosol sample; accessing a true barcode level of the barcode contained in the tracer test load; and deriving a calibration factor for the environment based on a difference between the detected barcode level and the true barcode level. The method further includes, during a live period succeeding the calibration period: triggering collection of a first bioaerosol sample by the air sampler; accessing a detected pathogen level of a pathogen detected in the first bioaerosol sample; and interpreting a predicted pathogen level of the pathogen in the environment based on the detected pathogen level and the calibration factor.
