Security Alarm System is the combination of three circuits which are main circuit, transmitter and receiver. With an aid of this project, the difficulty of intruder to split the entry can be solved. In this project is having one sensor which is door magnetic switch. The magnetic switch is controlled by the IC NE555. This component act as main or major part in the circuit. This component acts when the magnetic switch is changed. In this project, it uses 9V to 12V by the voltage regulator.
