Smart Sensor Car Scent Diffuser

Vehicles fragrance dispense with auto-on/off functionality are a relatively new vehicle scent solution. 

Auto-on/off can be best understood by understanding what 'smart diffuser' does to separate itself from lower end vehicle air fresheners hanging from the rearview mirror or clipped in a vehicle air vent. 

The 'smart diffuser' does one very important thing: it automatically knows when to start and stop!

How It Works

The core of the following auto-on/off functionality is a sensor, most likely a vibration or motion sensor.

Movement Detection: When the vehicle is started, and the transfer of subtle vibrations are detected, you are underway.

Activation: The sensor will turn on the diffusion of the fragrance. This may be via a fine mist of essential oils, or the scent may be from a distance dry sachet.

Standby: When parked and the engine is off for a specified time period (usually a minutes or two), the absence of your devices vibrations will signals the device to automatically turn off. This is beneficial because the fragrance is not being dispensed while unattended.

Adjustments: Smart diffusers usually have variable settings, meaning you can control fragrance intensity, and the length of time allocated to each fragrance blast. Depending on the price point where it is obtained, some higher institutional dispensers now have a blue-tooth connection and associated app for smartphone control of the scent frequency being dispensed.
