This project is developed for the users to control the operation of a door automatically.
When a person is about to go inside the door, it automatically traces that some one is waiting to enter.
The sensor connected with the door senses and sends a signal to the circuit. The circuit produces corresponding voltage and gives to the motor forwardly or reversal according to the signal produced. Thus the door is opened or closed according to the signal.
The door automatically senses that whether the person is entering into the door or leaving out of the door. This system is very useful in institutions, companies where there is crowd. In future this can be implemented with the help of a card system, in which only authorized persons can enter
