A simple and effective motion detector to sense the presence of dangerous animals nearby using a PIR sensor, Piezo buzzer, and LED connected to an Arduino Uno.
This system works by detecting infrared radiation emitted by warm-blooded animals and immediately alerts nearby people using visual (LED) and auditory (buzzer) signals. It is designed to be low-cost, portable, and easy-to-use, ideal for areas prone to animal encounters.
- Detects nearby movement using a PIR sensor
- Alerts via LED and Piezo buzzer
