The purpose of this project is to design, build and test a microprocessor-based
security system that works with a telephone. The system is activated remotely
by dialing the telephone numbers. The system should be able to turn on
some lights, sensors and provide status reports, upon request from the
caller. An alarm will go on once the sensors sense a rise in temperature,
movement or sound. The controller is developed using a single chip microcomputer
MC68705R3. Commands from the caller via telephone numbers are decoded using
a tone decoder. A voice synthesizer is used to send the status reports
to the caller.
