SMART HOME APPLIANCES USING ARDUINO AND RELAY

Smart home automation connects household devices with controllers, sensors and communication modules. • Home automation is growing with the Internet of Things (IoT), microcontrollers and affordable sensors. • Arduino Uno can read inputs and control electrical loads through a relay driver. • This project demonstrates a low-cost way to switch lights, fans and other suitable appliances. • The system can be expanded with Wi-Fi, mobile apps and energy monitoring. • Key point: Project focus: convenient control, improved energy use and safer operation when correctly designed.
