Programmable Home Security Alarm System
In this project we design high performance programmable home and there is no need to contact a company like Safemart home security for setup. This system uses a few LDR's as input sensors. When above sensor(s) get triggered system may dial the user specified phone number (using build-in DTMF ) and activate the high power audio alarm and lights. All the parameters of DTMF generator, audio alarm and light interface are programmed through the RS232 serial interface.
Current firmware of this system presents interactive control system through the RS232 interface. This control system consist with the menu driven configuration options, self tests, system report generators, etc.
This system also contain 5W (with 4Ω speaker) audio alarm with three selectable tone configurations, which include , Fire engine siren and Ambulance siren
