| Summary: | Uncertain weather changes can have a bad impact on farmers. Changes in weather can affect the fertility of agricultural land. The level of soil fertility in terms of soil temperature parameters, soil pH, and soil moisture. Weather that is too hot can make the soil temperature high and soil moisture low so that a lot of water is needed from irrigation canals. Meanwhile, during the rainy season, soil temperature decreases and humidity increases. Excess water in rice fields needs to be channeled to other rice fields through irrigation channels. In light of these issues, the purpose of this study is to design a mechanism that is capable of autonomously opening and shutting the irrigation door. When the irrigation gate may be opened and closed automatically is determined by soil fertility characteristics like temperature, pH, and humidity. This system is also equipped with a soil fertility monitoring system so that farmers can monitor the condition of their agricultural land in real time via smartphones. In general, the irrigation system may automatically open and shut the irrigation door, and the soil fertility monitoring system can become part of a single Internet of Things (IoT) system that is linked to a smartphone. A temperature sensor component, a pH sensor component, a humidity sensor component, an Arduino NodeMCU ESP32 as a CPU to process data from each sensor and also plays a part in delivering data to smartphones, ultrasonic sensor components, relay components, and a DC motor as an irrigation door driver make up the whole of this system. © 2023 IEEE.
