  Introduction  An AutomaticDoor Opener System is a simple project based on PIR Sensor and Arduino, which automatically opens and closes the door by detecting a person or object.  You might have seen Automatic Door Opener Systems at 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, there is significantly less loss of air conditioning.

   OVERVIEW  Inthe Automatic Door Opening System, the main component or hardware is the sensor which detects the persons (well, the motion of the person in our case). For this purpose, we will be using the PIR Motion Detector Sensor.  We have already seen in the Arduino PIR Sensor Tutorial about how a PIR Sensor Works and how to interface a PIR Sensor to an Arduino.  For the purpose of demonstration, I have used a CD Tray to replicate the door. Whenever the PIR Sensor detects a motion, the CD Tray opens and then closes after some time.  In order to control the 5V DC motor in the CD Tray, I’ve used the L298N Motor Driver Module. I’ve already done a tutorial on controlling a DC Motor using Arduino and L298N Motor Driver Module.

  Component Description  ArduinoUNO  In this project, Arduino UNO acts as the main controlling part. It reads the data from the PIR Sensor and activates the L298N Motor Driver based on the data from the PIR Sensor.  L298N Motor Driver Module  Motor Driver is an important part of the project as it is responsible for driving the motor of the door (CD Tray Motor in this case). In this project, we have used the very common and very popular L298N Motor Driver Module

  Working of AutomaticDoor Opener System  The working of the Automatic Door Opener System using Arduino and PIR Sensor is very simple. This project can be considered as an extension of Arduino PIR Sensor Tutorial and Arduino L298N DC Motor Control Tutorial.  When the PIR Sensor detects any motion of a person, its Data OUT Pin will become HIGH. As this pin is connected to the Arduino, it will detect this HIGH Signal and understands that there is person approaching the door.  Arduino then immediately activates the L298N Motor Driver module to open the door. After some time (about 2 to 5 seconds in this project), the Arduino will once again activate the Motor Drive to close the door.

  Applications  Arduino basedAutomatic Door Opener System is a very useful project as it enables you to understand the concept of such automatic door opener systems and how they work.  These systems are already being used in many places like malls, theatres and hospitals.  You can implement this Arduino based project at you home in Garage Door Openers, toilet cover openers, Office door openers, etc.
