Analog Project: Under The Guidance Of: Dr. Sathiya Narayan

This document summarizes an analog fire detection and alarm system project created by a group of students. The circuit uses a thermistor to detect changes in heat from a potential fire and triggers a transistor to activate a siren or buzzer alarm. The simple, low-cost system can be used for home and industrial security applications like warehouses to detect fires and alert people. The advantage is it provides an audio alert when heat is detected, making it an efficient, simple solution for fire detection and prevention.

Topic: Fire Detector and Alarm
system
 Fire Alarm Circuit is a simple circuit that detects the fire and
activates the Siren Sound or Buzzer. Fire Alarm Circuits are very
important devices to detect fire in the right time and prevent any
damage to people or property.
 Fire Alarm Circuits and Smoke Sensors are a part of the security
systems which help in detecting or preventing damage. Installing
Fire Alarm Systems and Smoke Sensors in commercial buildings like
offices, movie theatres, shopping malls and other public places is
compulsory.

Component Used:

 Breadboard
 1k ohm resistor
 47 ohm resistor
 BC 547 transistor
 9v battery
 10k thermistor
 Wires
Circuit Diagram:
Application:

 Home security
 Protect valueable in go-downs
 Museums
 Theatre
 Industries
 All electric Department
Advantages:

 Low cost
 Less complex circuitry
 Portable
 Simple and efficient
 Useful to save lives
Conclusion:

 The advantage of it is it gives sound alert from the fire alarm when
there is fire attack in the industries.
 It is more efficient , simple and less complex circuit
 It is used for the security of the warehouse where the storage and
protection of goods is the priority of concern .
 It is used for home security purpose too.
 The circuit uses the thermistors heat sensing property to sense the
heat and make us alert.
