2. Working Procedure
THIS FULLY AUTOMATIC FIRE DETECTION AND ALARM
SYSTEM IS EQUIPPED WITH AN IR RECEIVER AND A UA741
OP-AMP IC. THIS FIRE DETECTION CAN SENSE
TEMPERATURE CHANGES AND SOUND AN ALARM IN CASE
OF FIRE.
Objective
When a fire breaks out, time is short and quick
action is needed to evacuate trapped people before
the fire gets out of hand. However, to accomplish
this we need a system that can detect fires before it
is too late. And this system will do this.
