SECURE IOT-BASED HOME AUTOMATION WITH REAL-TIME MONITORING USING ESP32-CAM AND GOOGLE ASSISTANT

Abstract

This project presents an IoT and Google Assistant-based Home Automation System with Surveillance Camera using ESP32-CAM and ESP8266 microcontrollers. The system enables users to remotely monitor and control household appliances through voice commands and internet connectivity. The ESP32-CAM functions as a web server, providing real-time video streaming for home surveillance and security monitoring. The ESP8266 is connected to the Google Assistant through the Blynk/Cayenne/IoT platform (or suitable cloud service), allowing users to control electrical devices using voice commands from smartphones or smart speakers. The system integrates multiple sensors, including the DHT11 temperature and humidity sensor, MQ-7 carbon monoxide gas sensor, and a fire sensor to continuously monitor environmental conditions and detect hazardous situations. Upon detecting abnormal temperature, gas leakage, or fire, the system generates alerts and can automatically activate safety measures. Three relay modules are used to control a 12V fan, 12V light, and 12V motor. A 5V power supply powers the microcontrollers and sensors, while a 12V supply drives the connected appliances. The combination of IoT technology, voice control, environmental monitoring, and live video streaming provides an efficient, low-cost, and intelligent home automation solution that enhances convenience, safety, energy management, and security.
