Abstract This project implements a WiFi-based smart home system using an ESP32 microcontroller. The system integrates motion, temperature, humidity, and light sensors to automate a relay and servo mechanism and sends alerts via Pushover app when motion is detected in Away mode. A web interface allows toggling between Home and Away modes. The system prioritizes real-time motion detection using FreeRTOS task scheduling.
