Abstract
Automatic door opening system is a system which satisfies the need of opening a door. Some of the shopping malls can utilize this idea. We can see securities standing in front of these malls to open the door for the customers. This project gives an innovative idea to replace that system using simple electronic circuits.
As the customer reaches the front of the shop, its door will be open automatically in front of the customers.

The main parts of this project are PIC microcontroller, PIR sensor and Driver.PIR sensor is used to detect the presence of human beings by movement. When a person stands in front of the door, PIR sensor detects. Driver circuitry will be activated according to the input from the PIR sensor. The door can be opened by the motor which is driven by the driver circuit.
