Automatic Door Opening System

                                         Automatic Door Opening System

INTRODUCTION:

                        This project is based on a PIR sensor and Arduino, which automatically opens and closes doors by detecting persons or objects. You might see these systems at hospitals, malls, etc. 

When the PIR sensor detects any motion, its data out pin will become HIGH which is attached to the Arduino. As this pin is connected to the Arduino, it will detect this HIGH signal and understands that there is a person approaching the door, then Arduino immediately activates the L293D motor driver module to open the door. After some time, the Arduino will once again activate the motor drive to close the door.

COMPONENTS REQUIRED FOR THIS PROJECT: 

• Arduino UNO (R3)
• PIR sensor 
• Logicstate 
• DC motor
• LM016L
• L293D Motor Driver

COMPONENT DESCRIPTION:

• Arduino UNO (R3)

                          It read the data from the PIR sensor and activates the L293D motor driver based on the data from the PIR sensor. 

• PIR Sensor

                        Detecting the motion. 

• L293D MOTOR DRIVER:

                      It is responsible for the driving of the door motor.
