Multi Zone Fire Alarm System Using Mega32 Microprocessor

Multi-Zone Fire Alarm System Using Mega32 Microprocessor

Introduction We designed a multi-zone fire alarm system with a VT100-compatible user interface. The system is microprocessor controlled using the Mega32 microprocessor. The system communicates to the VT100-compatible user interface via a RS232 connection. A fire is detectable by a number of fire detection devices in each of as many as eight zones. High-level Design

Clifford Systems JI1000 Car Alarm System

Introduction The design philosophy behind the JI1000 is a simple, yet powerful microcontroller based mobile security system. At the heart of the JI1000 is the Atmel AT90S4414 8-bit RISC microcontroller. We used the 4414 for this design because a microcontroller is well-suited for a security system. The basic control functions for our system include monitoring
