: Requires connecting a PIR sensor (e.g., HC-SR501) to a GPIO pin.

The is a powerful, low-cost microcontroller that combines Wi-Fi/Bluetooth capabilities with an integrated camera module. For motion detection, you can choose between a hardware-based approach using an external PIR sensor or a software-based approach using image processing. Motion Detection Methods PIR Sensor (Hardware-Based): esp32-cam-motion-detection

: Low power consumption (ideal for battery operation) and high reliability with fewer false positives. : Requires connecting a PIR sensor (e

: Uses libraries like the Eloquent Arduino library to compare consecutive frames for pixel changes. esp32-cam-motion-detection

: Typically comes with the OV2640, supporting up to 1600x1200 resolution.

: No external hardware needed; allows for custom "detection zones" and sensitivity levels.
