1.Introduction

a. Statement of Purpose

The goal of this project is to create a device which, when triggered by a motion detector or pressure sensor, can perform a function such as beginning a video recording or triggering an alarm. This can have many uses, from basic home security, to catching whoever is stealing the last slice of pizza from the fridge, to even recording wildlife. 

b. Background Research

Most home security camera systems cost well upwards of $100, which is a fairly significant chunk of money for most people. We hope to be able to build something for those who do not necessarily need the greatest quality, that will cost less. To help us learn how to utilize the Arduino there are many tutorials online covering pretty much every topic we will need.


2.Design Details

a. Block Diagram

b. System Overview

When the burglar is detected either by the infrared sensor or the pressure sensor, the sensor sends signal to Arduino, which then activates a camera (or the so called "monitor") to start recording to keep track of the burglar. The camera is operated under the control of a servo motor, which allows the camera to rotate so as to reduce the blind area as much as possible.

3.Parts

1.Arduino

2.Infrared sensor

3.Pressure sensor

4.Camera

5.Servo Motor

4.Possible Challenges

1.Our lack of programming experience. Utilizing Arduino to enable the camera run by the servo motor to operate requires some fundamental knowledge about software programming.

Comments:

I like your guys' project! Designing the physical mechanism for starting/stopping the camera might be a little tricky, but with 3-D print and the machine shop should be possible.


Additionally, make sure you satisfy both the sensor (110) and logic element (120). For this project, you might be able to get by without using any kind of Arduino! If you are interested in trying to do it without any microcontroller, you'd use a few more logic elements which would satisfy the requirement.


Project approved, but please update your page with a comment about how you will use a logic element.

We'd like to incorporate three sensors (pressure sensor, infrared sensor, and ultrasonic sensor) that are operated under logic gates in addition to using Arduino.

I talked with you this evening and I think that this will be a good project. Just remember that you will want to focus on the sensory and logic portions of the circuit more than the camera itself.
