Abstract	Energy conservation is a crucial aspect of modern electrical and electronic systems, and automation plays a significant role in optimizing energy usage. This paper presents an intelligent energy-saving system utilizing an Arduino microcontroller to automate the control of electrical appliances such as lights and fans. The system integrates three primary sensors: a Passive Infrared (PIR) sensor to detect human presence, a Light Dependent Resistor (LDR) to monitor ambient light levels, and a DHT11 sensor to measure temperature and humidity. The Arduino microcontroller processes sensor data and executes predefined logic to control the connected appliances efficiently. This smart automation system offers an energy-efficient solution for residential and commercial applications. By reducing manual intervention and preventing energy wastage, it significantly contributes to sustainability efforts. The proposed system demonstrates the potential of sensor-based automation in reducing electricity consumption and enhancing convenience, making it a viable solution for smart buildings and energy-conscious environments.
