Welcome to the Arduino-PIR-Motion-Detector wiki!

Project Idea

For my midterm in ECE 387 Embedded Systems Design, I wanted to create a low cost motion detector to see how long someone has been in a room. My inspiration came from getting tired of waiting to use the shower in the morning. Before, I had no idea how long the person in front of me had occupied the shower. Now with this project, I can visually see, using leds, how long the person has been in the shower.

Summary of Results

I was able to implement a working system that would light leds and emit a noise when the time reached too long. The code could be improved with a timer library but what I have written works enough for the application. There a a few known issues that are discussed later on in the wiki. Please continue through the wiki to see how I implemented a PIR Motion Detector with an Arduino Uno for a low cost security/alarm system.
