Abstract: This paper presents the design of the low cost Electronic Eye Security system using LDR. Security is one of the most vital concerns of our daily life and properties in our environment. Electronic Eye is also known as magic eye. It makes sure that there is a constant watch on your doors. Imagine if you are alerted each time someone is trying to enter your home or work place. This also provides security when any person is trying to enter into your home without your permission. This helps you to take precaution before the damage has occurred. It is one of the most helpful devices in today’s security system. The main principle of the circuit is to ring the door bell when there is any person at the entrance. In order to detect a person, an LDR is used as the sensor. Light on the LDR determines whether a person is present or not. When there is any object at the entrance, LDR is in dark and buzzer starts ringing and the LED starts glowing.
