ABSTRACT
Engineering is not only a theoretical study but it is a implementation of all we study for creating something new and making things more easy and useful through practical study. It is an art which can be gained with systematic study, observation and practice. In the college curriculum we usually get the theoretical knowledge of industries, and a little bit of implementation knowledge that how it is works? But how can we prove our practical knowledge to increase the productivity or efficiency of the industry?
Don’t take the chance of becoming victim of burglary, which is often accompanied by violence. Protect our family and valuables with this microcontroller based security system that will let us rest our head knowing that should anyone trying to break into our home, an alarm will go off and the police will be alerted immediately.
The transmitter section continuously transmits IR rays which are received by the receiver section. The received signal is further amplified and given to the PLL section, where its frequency is locked to the transmitted frequency.
When the IR signal is interrupted, the microcontroller starts working as per the program burnt into the EPROM and control the siren, telephone and cassette player via the respective relays.

Most of us are not concerned of the security of the homes until we experience a burglary or sort of incident. The primary aim of this project is to provide total security to the house. This system employs a microcontroler as its central part and day and night detection is also enebled. The security precautions include aser beam monitoring system for windows, and magnetic monitoring for doors. The alarm system included in the system notifies the owner if there has been an intrusion or an attempt to break into the system. a 7 segment display with a 4x3 keypad is the source of input and user output.
The 20pin At89c2051 microcontroller is the heart of the project. A 5 digit pin entered by the user activates or deactivates the door lock security. The # and the * key serves as the enter and the backspace keys respectively.
The day and night detection is implemented using a Light dependent resistor (LDR). digital input output logic and analog information process is thus utilised here. The the voltage obtained can be used as a measure of the light falling on the LDR. The ADC of the microcontroller has to be put to use for this purpose. With this the task of turning on and off of the light is taken up by the microcontroller.
