  2. Original PDR Specifications • Real-Time counter for the number of people entering and exiting each room in a building • Account for the difference between a person entering and exiting • Reasonably accurate • Calculate evacuation route in case of an emergency • Account for possible traffic flow • Arrows displaying guided path to nearest emergency exit

  3. Adjusted Specifications • Real-Time counter for the number of people entering and exiting each room in a building • Detects direction of motion, whether entering or exiting the room • Reasonably accurate • Detecting people in single file rather than simultaneously • Can only count one person at a time • Two people can’t walk in and out at the same time • Should only take about 1 to 2 seconds max to walk through the door

  4. Power Consumption • External Power Source – 12V • Components • Arduino + Wifi shield 200mA-800mA • Grid Eye Sensor – 3.3V, 10uA • Wireless Shield - ~300mA

  5. Component Price • Arduino Uno Single Board Microcontroller $27.95 • Arduino Wireless Shield $84.95 • 12 VDC 1000mA Adapter $8.95 • Panasonic Grid Eye IR Sensor(Breakout) $39.21($75.14)
