Design and Construction of Microcontroller-Based Fire Detection and Control System
Subject area: Science,Engineering and Technology · Area of research: Embedded Systems and Automation
Abstract
This project presents the design and construction of microcontroller-based fire detection and control system. The system senses dense smoke fumes and high temperatures that lead to fire outbreak with the aid of a sensing circuit made up of a photoelectric smoke sensor and a negative temperature coefficient thermistor, respectively. The sensory circuit is connected to a NPN transistor in parallel to each other, when the OP-Amps output is high the transistor turns on and the base current of the transistor switches on the buzzer once it senses smoke or high temperature and the other output of the transistors is connector to a Peripheral Interface Controller (PIC16F877A) microcontroller. When the microcontroller is set at high pin configuration it sends a message to the fire extinguisher unit, which automatically switches on and then releases 〖CO〗_2 gas in the form of a message. The other end of the microcontroller is interfaced with LCD which serves as monitoring and supervisory station. The sensory and interfacing circuit are both powered using a 5V regulated power supply. This system improves the chances for reducing the risks to life and property.
