Abstract: This paper presents the design and implementation of an automatic fan regulation and smart curtain system aimed at enhancing energy efficiency and user comfort. The system integrates temperature and light intensity sensors with microcontroller-based automation to dynamically adjust fan speed and curtain positioning. The fan speed is regulated based on ambient temperature, ensuring optimal cooling while conserving energy. Simultaneously, the smart curtain responds to light intensity, adjusting its position to maintain appropriate indoor lighting conditions . The proposed system offers an affordable and sustainable solution for smart home applications, combining ease of use with significant energy savings. Experimental results demonstrate its effectiveness in achieving the desired automation objectives.
