This project is developed for the users to give very high security to modern houses using PLC kit.
It mainly consists of four IR transducers, PLC kit, ADC, 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 senses and it sends signal to the ADC. The ADC sends signal to the PLC kit. The PLC is programmed to operate the telephone unit and buzzer according to the input signals.
Accordingly the PLC kit 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 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
