This research developed an Internet of Things (IoT)-based Smart Home system for monitoring and controlling room temperature using the DHT22 sensor. The system utilizes an ESP32 microcontroller and Node-RED platform to process real-time temperature data transmitted via the MQTT protocol to a Raspberry Pi server. The DHT22 sensor measures the room temperature, and the data is sent to the ESP32 for processing and visualization by Node-RED. The Raspberry Pi serves as the control center, enabling temperature monitoring and control through a mobile application. The system automatically controls a fan based on room temperature, where the fan turns on when the temperature exceeds 30°C and turns off when the temperature drops below 30°C. Additionally, users can manually monitor the temperature and control the fan via the mobile application. Test results show that the system functions well, making it easier for users to control the fan.
