This study develops a Smart Room System based on the Internet of Things (IoT) to enhance comfort and energy efficiency in boarding rooms by integrating automatic control of temperature, ventilation, and lighting. The system uses a DHT22 sensorr to monitor temperature and humidity, a PIR se to detect occupant and control lighting, a servo motor regulate ventilation, and a DC fan as the temperature controller. All components are managed by an ESP32 microcontroller connected to a web dashboard that enables real-time monitoring and remote control. The research methodology includes requiments analysis, system architecture design, web server develoment, hardware softwae integration, and functional testing. The test result indicate that the system operates automatically and reliably, the fan and servo active when the temperature exceeds the threshold, and the light turn on when the PIR sensor detects motion. Manual control via the web interface also functions effectively with low latency (0.5-1 s). In conclusion, the Smart Room System succesfully improves energi efficiency and provides convenient remote control, althrough it remains dependent on a stable Wi-Fi connection for monitoring and manual control features.
