This report details a project focused on the development of a low-cost, microcontroller-based fire alarm system (M-FAS). The project aims to design, prototype, and implement a user-friendly fire alarm system utilizing heat, flame, and smoke detectors. The system incorporates a PIC16F877A microcontroller to control operations, including sensor input, alarm activation (buzzer, strobe light), and a monitoring system. The project includes detailed descriptions of the system's components, engineering knowledge applied, and the role of the project manager. The report also compares the cost-effectiveness of the developed system with commercially available alternatives and addresses project management aspects such as scope definition, procurement, documentation, and cost control. The system's design incorporates parallel connections of sensors to prevent false alarms and utilizes a GUI for monitoring. The report discusses the application of engineering principles, including microcontroller programming and circuit design, to achieve the project's objectives. Furthermore, the report includes details of the project manager's responsibilities, including defining scope, managing documentation, and coordinating with clients and team members. The project's distinct activity is the development of a front panel GUI for monitoring and the use of specific components like LM741 and 2SC9012 for heat detection and relay actuation.
