Home Security System

Detects motion using a PIR sensor connected to an ESP32, triggers a buzzer, and sends an alert to PxServ. The system can be remotely disabled by updating the system_status key via the PxServ dashboard or API.

Hardware: ESP32, PIR motion sensor, buzzer Libraries: WiFi.h, PxServ.h
