Motion Activated Automatic Room Freshener [ DIY ]

Motion Activated Automatic Room Freshener.
In this DIY project, we are using a PIR Motion sensor module, a DC Fan, normal room freshener and 5V Power Supply.
Working- Fan will turn ON when motion is detected by the PIR(Passive Infra-Red) sensor. This Fan is mounted in exhaust mode i.e. air inside the box will be blown out so when motion is detected, or if anyone is present inside the room, then the Fan will turn ON and a breeze of scented fresh air will dissolve in room air. The fan will automatically turn OFF when no motion is detected for some time. For example- If this automatic Room
Freshener is kept in a Washroom, then Fan will turn ON If someone enters the washroom and fan will automatically turn off after leaving the washroom.
[ PIR sensor can only detect warm bodies such as Human or Animals ]
