Key Features:

• Low-Cost & Easy: Affordable and straightforward to build.

• Sprinkler System: Releases water automatically when fire is detected.

• Early Warning: Activates a buzzer to alert you to potential fire hazards.

• Customizable: Can be expanded and adapted for various applications.

• Versatile: Suitable for home, office, and other fire-prone areas.

Project Overview:

This system operates as follows:

1. Flame Detection: The flame sensor detects the presence of fire.

2. Alarm Activation: The buzzer sounds to alert individuals.

3. Water Release: The system activates a mini water pump to release water, helping to extinguish the fire.

Note: This is a basic implementation. You can enhance it with features like temperature sensors, smoke detectors, and more sophisticated water spraying mechanisms."

And here's the revised component list:

OK, let’s do this project step by step. The required components are given below.

• Arduino Nano board x 1

• Flame sensor x 1

• Relay module x 1

• Buzzer x 1

• Breadboard x 1

• Jumper wires

• Mini water pump

• Mini water pipe

Making Process: Step-by-Step

1. Gather Materials:

• Arduino Nano board

• Flame sensor

• Relay module

• Buzzer

• Breadboard

• Jumper wires

• Mini water pump

• Mini water pipe

2. Connect Components:

• Power Supply:

  • Connect the Arduino Nano board and other components to a suitable power source (e.g., 5V DC power supply).

• Flame Sensor:

  • Connect the VCC pin of the flame sensor to 5V.

  • Connect the GND pin of the flame sensor to ground.

  • Connect the output pin (usually labeled as "DO") of the flame sensor to a digital input pin on the Arduino.

• Buzzer:

  • Connect one leg of the buzzer to a digital output pin on the Arduino.

  • Connect the other leg of the buzzer to ground.

• Relay Module:

  • Connect the VCC and GND pins of the relay module to 5V and ground, respectively.

  • Connect the input pin of the relay module to a digital output pin on the Arduino.

  • Connect the output pin of the relay module to the positive terminal of the water pump.

  • Connect the negative terminal of the water pump to ground.

3. Develop and Upload Code:

Arduino Code
/*Fire protection system with Arduino */ #define flame 2 #define relay 3 #define buzzer 4 void setup() { Serial.begin(9600); pinMode(flame, INPUT); pinMode(relay, OUTPUT); pinMode(buzzer, OUTPUT); digitalWrite(relay, HIGH); } void loop() { bool Svalue = digitalRead(flame); if (Svalue == 0) { digitalWrite(relay, LOW); digitalWrite(buzzer, HIGH); delay(300); digitalWrite(buzzer, LOW); delay(300); digitalWrite(buzzer, HIGH); delay(300); digitalWrite(buzzer, LOW); delay(300); digitalWrite(buzzer, HIGH); delay(300); digitalWrite(buzzer, LOW); } else { digitalWrite(relay, HIGH); } }

• Write the Code:

  • Use the Arduino IDE to write the code.

  • The code should:

    • Read the digital input from the flame sensor.

    • If the flame sensor detects fire (output is HIGH):

      • Activate the buzzer by setting the corresponding digital output pin HIGH.

      • Activate the relay by setting the corresponding digital output pin HIGH, thereby turning on the water pump.

    • If no fire is detected:

      • Deactivate the buzzer by setting the corresponding digital output pin LOW.

      • Deactivate the relay by setting the corresponding digital output pin LOW, turning off the water pump.

• Upload the Code:

  • Connect the Arduino Nano board to your computer via USB.

  • Upload the compiled code to the Arduino Nano board using the Arduino IDE.

4. Test and Calibrate:

• Power On: Power on the system.

• Test Flame Detection: Simulate a fire (e.g., using a candle or a lighter) near the flame sensor.

  • Verify that the buzzer sounds.

  • Verify that the water pump activates.

• Test False Alarms: Test the system in normal conditions to ensure that it doesn't trigger false alarms.

• Adjust Sensitivity: If necessary, adjust the sensitivity of the flame sensor to minimize false alarms.

5. Refine and Customize (Optional):

• Add Enhancements:

  • Incorporate a temperature sensor to provide additional fire detection.

  • Add a smoke detector for early warning.

  • Implement a more sophisticated water spraying mechanism.

  • Integrate with a home security system for remote monitoring and control.

• Improve Aesthetics:

  • Enclose the system in a suitable enclosure.

  • Improve the overall appearance of the system.

Note:

• This is a basic implementation. The specific wiring and code may vary depending on the components you use and the desired features.

• Refer to the datasheets of the components for detailed specifications and pinouts.

• Always exercise caution when working with electricity and water.

This step-by-step guide provides a foundation for building your basic Fire Protection System. Remember to experiment, learn, and prioritize safety throughout the process.
