Automatic deodorizer dispenser
Automatic perfume or air freshener dispenser
From Wikipedia, the free encyclopedia
An automatic deodorizer dispenser is an air freshener designed to release the encapsulated scent at a set time, or under preset conditions. Some fresheners operate by releasing a quick burst of scent every nine minutes, 18 minutes, or 36 minutes so the user does not become too accustomed to the smell. Other kinds operate by having a light sensor or motion sensor attached, and releasing a burst of fragrance whenever this sensor is tripped.[1]
Each bus of TransJakarta is equipped with automatic air freshener dispensers which periodically spray car fragrance in order to keep the air fresh.
