Design and Implementation of IoT-Based Aeroponic Farming System

Urban farming becomes popular and enhances food security in urban areas. Aeroponic is one of the urban farming methods where plant roots are suspended in the air and are supplied with nutrients by mist spraying. This paper describes an IoT system for monitoring and controlling evapotranspiration in an aeroponic environment. The system consists of a microcontroller, single-board computer, sensors, and actuators. The sensors in the system collect the data on plant environment parameters including air temperature, humidity, total dissolved solids (TDS), pH, and water temperature. Then, the system calculates the level of evapotranspiration using the Blaney-Criddle method to determine the appropriate actuator action to reduce the level of evapotranspiration in aeroponic using a fuzzy algorithm. The experimental result shows that our IoT system can reduce evapotranspiration, hence, it can improve the plant quality.
