Rapid advances in the Internet of Things (IoT) have transformed automation, especially in smart home applications. This study presents the design and implementation of a smart home system built on the NodeMCU development board (ESP8266) and integrated with a set of environmental and security sensors. The proposed system allows users to monitor conditions and control household devices remotely via the Blynk IoT platform, providing a flexible, low-cost, and energy-efficient solution. The hardware configuration includes sensors for temperature, humidity, air quality, motion, light intensity, and obstacle detection, in addition to actuators such as servo and DC motors for automating a garage door and curtains. An OLED display provides on-site environmental readings, while the Blynk mobile application enables real-time control over Wi-Fi. Experimental testing confirmed stable connectivity, responsive control, and reliable continuous operation. The modular architecture also supports easy expansion and customization to meet different residential needs. Overall, the results demonstrate that open-source IoT platforms can deliver scalable, cost-effective, and sustainable smart home automation.
