Step-by-Step Instructions
Set Up Jungle Camera Trap
Position PIR motion sensor and NFC reader at the jungle waterhole trail.
Move Tiger Figure Past Sensor
Move Tiger figure past the PIR sensor. Motion triggers camera trap LED flash!
NFC Tag Census Identification
NFC reader scans Tiger ID tag. Speaker plays real tiger roar: 'ROAR! TIGER #04 DETECTED!'
Plot Wildlife Population Chart
After 15 animal passes, OLED displays census bar chart: 'Tigers: 6 | Elephants: 5 | Leopards: 4 | Total: 15'.
Why It Works & Notes
Chapter 10 focuses on animal data tallies and conservation statistics. Using PIR motion sensors and NFC tags to build a smart camera trap introduces wildlife census technology.
