Smart Electronic Security System for Residences with Auto Dialer

Abstract

Security is primary concern for everyone. This Project describes a design of effective security alarm system that can monitor home with eight different sensors. Fire accident, IR detection, and gas detection can be monitored by the status of each individual sensor and is indicated with an LED. This LED shows whether the sensor has been activated and whether the wiring to the sensor is in order. The burglar alarm is built around the AT89S52 micro controller from Atmel.
