Embedded Intelligent Security System project is developed for the users to give very high security to modern houses.

It mainly consists of four IR transducers, microcontroller unit, LCD display, Stepper motor and telephone circuit.

The four sensors are connected at the four sides of the house. When any one enters inside the compound, the sensor sends signal to the microcontroller. The microcontroller analyses the signal and recognize the particular side.

Accordingly it controls a stepper motor and also sends signal to a buzzer, Telephone circuit and LCD display. A top light is connected with the stepper motor. Thus the stepper motor rotates the top light to the particular side.

The LCD display displays the details. The telephone circuit makes a call to the owner.

Since the owner can easily understand the happenings while sitting inside the house, this project gives very high security.

The microcontroller used is PIC 16F73 and the microcontroller program is written in assembly language
