, which utilized aC/C++ language-based IDE (integrated development environment) platform. Arduino served asthe main controller, and basic algorithms and code samples are shown in Fig 2 and 3. For userconvenience, the system displayed overall status messages on the LCD monitor. A continuousloop syntax controls the data from the temperature and humidity sensors, soil moisture sensor,and light sensor. When specific thresholds were exceeded or errors occurred, the actuatorsresponded accordingly. Fig 2.
