Wireless Control System for Power Source Using RF433MHz Communication and AVR Microcontroller

Abstract

The implementation of a wireless control system for a 220V power source using RF433MHz communication and an AVR microcontroller (ATmega328P) marks a significant advancement in home automation and energy management. This system facilitates remote operation of electrical devices, enhancing both convenience and efficiency while supporting energy conservation initiatives. By leveraging RF433MHz technology, known for its reliable range and strong penetration capabilities, the system is well-suited for residential and industrial applications. The proposed design consists of three primary components: a transmitter unit responsible for sending control signals, a receiver unit integrated with the ATmega328P microcontroller to process commands, and relay modules to switch the 220V power supply on or off. This configuration enables remote device management, significantly reducing energy wastage and improving safety by eliminating manual switching requirements. Furthermore, the system can be extended with additional functionalities such as timers and automated scheduling, further optimizing energy use and aligning with the growing trend of smart home technology. This implementation underscores the integration of modern wireless communication with practical automation, offering a cost-effective, scalable, and efficient solution for remote power management. Through promoting sustainable energy consumption practices, the system paves the way for smarter and more eco-friendly living environments.
