Here to learn How to Make an Bluetooth controlled Automatic Door Opening and closing System Using Arduino, PIR Sensor HC-SR501 and android application, which automatically opens and closes the door by detecting a person and controlled by android app.
You might have seen Automatic Door Opener Systems at office, shopping malls, cinemas, hospitals etc. where, as soon as a person approaches the door (at about 2 or 3 feet), the door automatically slides open. And after some time (about 5 to 10 seconds), the door closes by sliding in the reverse direction.
Such Automatic Door Opener Systems are very useful as you do not need a person to standby the door and open it whenever a guest comes. Also, since the doors are opened and closed only when a person approaches the door. This automatic control and Stop control using bluetooth HC-05 through android application.
So, In order to understand the potential of this concept, we have implemented a simple Automatic Door Opener System using Arduino and PI
