Abstract:
The Fire Detection Alarm System circuit presented here uses a Flame Sensor, comparator IC LM393, and a relay. The Flame Sensor detects fire intensity, while the LM393 IC functions as a comparator. In the absence of fire, the flame sensor stops conducting, and the buzzer stays off. When fire is detected, the flame sensor starts conducting, activating the buzzer.
Application of the Circuit:
Most flame sensor-based circuits on the market require costly components and complicated circuitry. This circuit uses readily available flame sensors, reducing cost and complexity. The Fire Detection Alarm System circuit activates a buzzer upon detecting fire, providing continuous feedback.
Why This Particular Circuit:
The circuit operates on 5V DC and uses a Flame Sensor as the fire detector, making it cost-effective and reliable.
Explained Working of Circuit:
The IC LM393 is used as a comparator, processing the output from the flame sensor. In normal conditions, no fire is detected, and the buzzer stays off. When fire is detected, the buzzer activates. The relay serves as a switch to control the circuit’s operation.
How to Build:
Read the manual thoroughly and study the circuit and PCB layout provided. Solder the components according to the PCB layout. Use IC sockets for easy troubleshooting and replaceable ICs. Start soldering components from the left-most corner of the PCB, paying attention to component polarity.
Testing the Kit:
After assembling and soldering the components, connect a 5V external power source. Hold a heat source near the flame sensor to test. The buzzer should sound in response to the fire detection.
ICs Used:
The only IC used is LM393, a dual differential comparator commonly used in similar circuits.
