Opening and closing doors have always been tedious and boring work, especially in places where a person is always required to open the door for visitors such as hotels, malls, theaters, etc.Automatic door opening system are used In many places such as shopping centers, train or railway stations, airports, etc. To eliminate the manual opening and closing of doors.

Automatic door opening systems can be implemented using different sensors such as infrared, pressure, ultrasonic, laser, etc. This project deals with an interesting way of automating the process of opening and closing the door by detecting the presence of a human being.

Automatic door opener system circuit principle

The principle of the project lies in the operation of the PIR sensor. A PIR or passive infrared sensor, as the name implies, does not emit infrared rays, but only detects them.

All humans emit infrared radiation in the form of body heat. A PIR sensor will capture the difference between ambient temperature and body temperature as a change in infrared radiation.

This change in the infrared pattern becomes a voltage. The voltage of the PIR Sensor Data Output can be given to a microcontroller for further processing such as motor control, etc.
