Abstract: Storage of coffee beans is essential to maintain the quality of coffee in terms of water content and humidity. So we need a storage room with a stable temperature and humidity. In this research, we will design a post-harvest coffee bean storage system, by maintaining the condition of the room at a temperature of 19°-27°C with humidity of 60% -70%. The design uses block diagrams and wiring diagrams, then makes a coffee bean storage box by using a fan as an actuator, and a DHT 11 sensor to measure the temperature and humidity of the room. The results of this study are the Arduino -Uno based Arabica coffee bean storage box takes 7 hours to get the expected set-point. the storage room has a temperature of 19°-27°C and humidity 60-70%
