| dc.description.abstract | A tool has been designed for an automatic greenhouse opening and closing system with weather control based on the Arduino nano microcontroller. This tool is designed to keep plants in the greenhouse, where these principles when the weather sensor reads analog signals that occur in the surrounding area, then converts them into digital signals, servo motors act as roof drivers and then processed in the system, the data will be displayed on the LCD. . Open the roof lid automatically based on the weather sensor, the weather sensor will read the weather conditions around, the weather is sunny or bright at a temperature of 28-30 °C and when it rains above 100% then the roof opens, the weather is cloudy or rainy when the temperature is below 28° C and rainfall is below 100% then the roof is closed and the weather is hot or hot when the temperature is above 31 °C and the rainfall is above 100% then the roof is closed too. From the results of testing and measurement of sensor tools that can work well and can measure according to what has been determined. | en_US |
