Design and Implementation of an IoT based Energy-Efficient User-Friendly Smart Home Automation System for Energy Savings and Maximizing Comfort

In this Research, we proposed a novel approach to develope an energy-efficient home automation system based on IoT technology which can be operated through Google Assistant and Espressif Systems Platform for Rapid Integration and Deployment of IoT Devices with Cloud Connectivity (ESP Rainmaker) app, enabling seamless user experience and customization. The proposed system provides automated control of home appliances and monitors indoor temperature and humidity for providing more comfortable and energy-efficient living environment. The proposed system was then practically implemented using Espressif Systems Processor 32 bit microcontroller (ESP32), two 4 channel relay modules, an IR remote control, a DHT11 temperature and humidity sensor .These low-cost($20.75) hardware makes the system accessible to homeowners seeking to enhance their living spaces in a sustainable and efficient manner. This Research evaluate the significant improvements in temperature and humidity control with an 83% reduction in temperature fluctuations and a 71% reduction in humidity fluctuations. The system resulted in a 22.5% overall reduction in energy consumption, while the water heater showing the most significant reduction at 50% thus reducing the carbon footprint of the household to mitigate the challenges of the climate change.
