ESP32 Motion Alarm System (PIR + Buzzer + LED + Telegram)

A smart security alarm system that activates the buzzer and LED when the PIR sensor detects motion, while simultaneously sending an instant notification to the owner via Telegram. It includes a 30-second cooldown to prevent false alarms. Suitable for home security, garage monitoring, warehouses, or workrooms. With ESP32-CAM, photo notifications can be added; with the classic ESP32 DevKit V1, text notifications are sent.
