Motion Detection

PIR stands for Pyroelectric ("Passive") InfraRed sensor

For a brief explanation on what PIR is and how it works, follow LadyAda's tutorial here.

For this project, you will require

• A PIR sensor ( Dome preferred )

• An Arduino board. (I used the Arduino Mega 2560)

• Jumper wires

• USB cable to program the Arduino

• The arduino IDE correctly installed on your computer

I got all my parts from Element14 here

• Connect VCC to 5v on the Arduino.

• Connect Ground to GND on the Arduino.

• Connect the Digital OUT of the PIR sensors to Digital Pin 2 on the Arduino

The output on my serial monitor was:
