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
