The Occupancy Project

Opera Box Sensing Project

Goal: Detect when people are in the opera boxes.

Method 1: Detect how many people pass through the door**

Using: Ultrasonic Sensors


Method 2: Detect when there are any number of humans in the room**

(detects motion by using two IR sensors, and seeing when the readings pass between them)

  • All of these use basic IR sensors but then add more functionality.

  • So, I don’t believe any of these could just sense how much IR is in a room.

Just the sensor:

Experimentation Needed:

  • I would be interested in seeing what would happen if we use the PIR sensor set to very sensitive with “retriggering mode”.

  • Does it reliably detect human presence?

  • Can we tap into the sensors directly?
