IoT System Developer – Coffee Bean Drying Machine Project Hasanuddin University
Thesis
Designed and implemented an IoT-based rotary coffee bean drying machine using NodeMCU ESP8266 and DHT22 sensors.
Developed a mobile application to monitor and control drying machine parameters such as temperature and humidity in realtime. Programmed automated actuators, including motors, fans, and heaters, ensuring optimal drying efficiency. Enhanced user experience by integrating a Firebase database for seamless data storage and retrieval.
