<![CDATA[Classroom facility management in Building C of Universitas Pahlawan Tuanku Tambusai is currently still done manually, making the process of monitoring room conditions and controlling learning support devices less efficient. This research aims to design and build an Internet of Things (IoT)-based Smart room capable of monitoring room conditions and controlling devices in real-time. The research method used is a qualitative method with data collection techniques in the form of observation, interviews, and literature study to obtain the system requirements to be developed. The system is built using an ESP32 microcontroller as the control center, a DHT22 sensor for monitoring room temperature, an LDR sensor for monitoring lighting levels, a relay as a controller for lights and fans, a TFT LCD Touchscreen as a local monitoring and control medium, and the Blynk application as an internet-based monitoring and control medium. Test results show that the system is capable of displaying temperature and room lighting level data in real-time on the Blynk application and TFT LCD Touchscreen. Control of lights and fans can be done directly using the Blynk application or through the TFT LCD Touchscreen. The developed system is able to assist the monitoring and control process of room facilities, making it more effective and easy to use.]]>
