Intruder detection using ultra low powered thermal vision

Suppose you are alone at home or out for shopping or on vacations and someone breaks into your house. First thing comes into your mind is: if there is some gadget or home security system which can alert you or your neighbors. The home security camera does a good job but they may not work in complete dark. Also, you do not want your gadget to turn on false alarm if it is a cat. In this project I built a proof of concept which merely turn on an LED for demonstration purpose when it detects a person in light or dark using just a Raspberry Pi Pico and a low resolution thermal camera.
