Design and Implementation of Hybrid Security System Using PIR and Microwave Doppler Sensor

Abstract

Security system is something applicable to all of us and involves the hardware in place on a property, and personal security practices. The hardware would be the doors, locks, alarm systems, lighting, motion detectors, and cameras systems that is installed on your property. Security has becoming an important issue everywhere. Home security is becoming necessary nowadays as the possibilities of intrusion are increasing day by day. The system is controlled by ATmega 16 microcontroller. The microcontroller chip will incessantly supervise every sensor. In case the microcontroller senses any type of security problem, then it will send an SMS message to the registered user mobile that uses GSM modem.
