        Abstract:
        The Fire Indication System circuit is built using a Flame Sensor and comparator IC LM393. The Flame Sensor detects fire intensity, while the LM393 comparator processes the signal. In the absence of fire, the flame sensor stops conducting, and the LED stays off. When fire is detected, the LED glows, indicating the presence of fire.

        Applications:
        Most fire detection systems use complex circuitry, but this kit utilizes a simple, cost-effective Flame Sensor for fire detection. The circuit operates on a DC voltage of 5V, making it suitable for various electronic projects and educational purposes.

        Why this circuit:
        The circuit ensures reliable fire detection and works over a 5V DC supply. The Flame Sensor detects heat and outputs it to the LM393 comparator, which triggers an LED to glow in case of fire.

        Building Instructions:
        Start by reviewing the provided manual and the circuit diagram. Ensure correct placement and polarity for components during assembly. Use IC sockets for easy troubleshooting and ensure sensitive components like diodes and capacitors are soldered last.

        Testing:
        Connect a 5V DC power source, then manually hold fire over the Flame Sensor to test. Adjust the R2 variable resistor to set the desired fire detection sensitivity.

        ICs Used:
        LM393 – A dual comparator IC, widely used in fire detection systems.

        Part List:

        • U1: LM393 (8-pin comparator IC)
        • Flame Sensor (D4)
        • Red LED (D1)
        • Green LED (D2)
        • Resistors: R2 (10k Ohm, variable), R3, R4, R5, R6 (all 1k Ohm, 10k Ohm)
        • Capacitor: C1 (1uF)
        • 5V USB Cable
        • PCB
