What Makes a Diffuser 'Smart'?

Smart car diffusers are identified by a few essential features.

Auto On/Off:  A number of smart diffusers utilize vibration sensors, allowing the device to determine when the engine is running. This way the diffuser can release fragrance immediately upon driving. 

Plus, if you stop for a length of time, the diffuser will turn off, improving the longevity of any required batteries and essential oil's run time.

Adjustable Fragrance Intensity:  Unlike using a passive air freshener, smart diffusers typically offer adjustable fragrance intensity settings. Most offer a low, medium, and high settings so you can be in control when using essential oil in the car.

Programmable Timers:  Some smart diffusers even offer programmable schedules for scent, through a smartphone app. This means that you could select the diffuser to only run at certain times of the day, or for certain amounts of time.

Improved Fragrance Delivery:  Smart diffusers also use elements of advanced technology such as ultrasonic atomization or nanotechnology to bring you fine mists of essential oil. 

Better means of delivering scent allows for more reliable and consistent fragrance than passive methods of scent application.

Rechargeable Power:  Smart diffusers are usually cordless, as they run off a rechargeable lithium battery which have greater longevity than alkaline batteries. Rechargeable batteries can typically be recharged with a USB-C port.

LED Lights and Aesthetics:  Many smart diffusers also feature LED lights to add a modern look and feel to any car interior. And with many smart diffusers offering multiple colors or an optional 'starry projection,' they can help to set the mood in your car.
