Owing to advancements in control systems and network technologies, traditional campuses that used to require enormous amounts of labor in management are now transforming to ensure effective management based on the concept of the smart campus. We developed a smart sprinkler system on a university campus using AI technology. As a feature of the smart campus, the system for replacing the previous sprinkler system was built with sensors and modules. The smart sprinkler system measures weather data and soil properties using the micro-weather station designed in this study. Weather forecasts were also considered to decide whether or not to activate the system. People in the area of sprinkling were detected, and an e-fence was set around them in order not to spray water on them. The proposed sprinkler system coincided with the university’s plan to follow the policies under the Sustainable Development Goals (SDGs).
