This paper introduces an innovative FPGA-based window automation system designed for smart homes, leveraging advanced real-time environmental sensing to enhance conve- nience and energy efficiency. The system integrates a Field Programmable Gate Array (FPGA) with a rain sensor, a comparator, and a servo motor to autonomously control win- dow operations in response to rainfall, preventing water ingress without manual intervention. The rain sensor generates an analog voltage signal proportional to moisture levels, which the comparator converts into a digital signal by evaluating against a dynamic threshold, enabling precise rain detection. The FPGA, programmed in Verilog, processes this signal with low-latency control algorithms, driving the servo motor to adjust window positions seamlessly. A key innovation lies in the system’s adaptive control logic, which optimizes window movement based on rainfall intensity, reducing energy consumption and wear on mechanical components. The prototype, validated on a breadboard, demonstrates robust performance with minimal latency, achieving reliable operation under varying weather con- ditions. Unlike traditional microcontroller-based systems, the FPGA’s parallel processing capabilities ensure superior speed and flexibility, making it ideal for scalable smart home applications. The system also incorporates potential for integration with IoT platforms, enabling remote monitoring and predictive weather-based control through API connectiv- ity. Experimental results confirm the system’s effectiveness in preventing water damage while maintaining user comfort. Future enhancements include multi-sensor integration for comprehensive environmental monitoring and machine learning algorithms for predictive window control, positioning this system as a pioneering solution in smart home automation. This work underscores the transformative potential of FPGA-based designs in creating re- sponsive, energy-efficient, and user-centric home automation systems, offering a blueprint for next-generation environmental control technologies
