Automatic Fire Fighting System Athan Jefferson Advisor Dr. Junkan Ma Instructor Dr. Cris Koutsougeras ET 494 Senior Design II

Introduction

Objective To design and fabricate an automatic firefighting system prototype. To display the knowledge gained at Southeastern University

Methodology Use infrared sensors to detect a fire source and the distance the fire source is away from the system Use distance sensor to calculate distance away from source Use Arduino-uno microcontroller to controller infrared sensor, distance sensor, servo,and linear actuator. Use C programming algorithms to calculate the angle of water nozzle based on and water pressure distance
