Flame Detection System

Description

This project is aimed at developing a real-time flame detection system using an 8051 microcontroller. The system detects fires when they are still small, offering early detection capabilities at a low cost. It utilizes flame sensors to detect the presence of smoke or high temperatures, triggering an alarm through the microcontroller.

Hardware Requirements

• 8051 Microcontroller
• Flame Sensor
• LCD Display
• Resistors
• Capacitors
• Power Supply

Software Requirements

• Keil µVision IDE

Instructions

1. Connect the flame sensor to Pin P1.0 of the 8051 microcontroller.
2. Connect the LCD display to Port 3 of the microcontroller.
3. Ensure proper power supply to the system.
4. Compile and flash the provided code using Keil µVision IDE.
5. Upon detecting a flame, the LCD will display "Flame Detected".

Code Overview

• The code initializes the LCD display and continuously monitors the flame sensor.
• If a flame is detected, it displays "Flame Detected" on the LCD.
• The lcd_init() function initializes the LCD.
• The cmd() and dat() functions send commands and data to the LCD respectively.
• The lcd_string() function displays a string on the LCD.
• The delay() function introduces a delay for proper LCD operation.

Project Objectives

• Detect fires at an early stage.
• Develop a cost-effective real-time fire detection system.
• Improve accuracy and response time compared to conventional fire detectors.

Note

Ensure proper connections and power supply for reliable operation of the system.
