ARTMENT SECURITY SYSTEM ABSTRACT
ABSTRACT
The technological advancement of human civilization has forced us to modify every aspects of
our life to new standard. No parts of human life remain untouched from the technological
breakthrough Almost all the traditional method of accomplishing the daily work is heading
towards the development.
Security is the prime concern in our day-today life. Everyone wants to be as much secure as
possible. The project “APARTMENT SECURITY SYSTEM” is the study and design of
microcontroller based system that can be adopted in apartment security. This Project describes a
design of effective security alarm system that can monitor an apartment with five different
sensors. In our project we have smoke sensor, gas sensor, temperature sensor, IR sensor and
vibration sensor. The system is fully controlled by the 8 bit microcontroller AT89S52 which has
8 Kbytes of ROM for the program memory.
The microcontroller will continuously monitor all sensors and if it finds any security problem
like Fire accident, IR detection, and gas leakage etc. then it will switch on the Alarm until the
Reset button is pressed and the corresponding problem and apartment number is indicated in the
LCD placed at the central unit of the apartment building.
