Rancang Bangun Sistem Irigasi Otomatis dan Monitoring pada Lahan Pertanian Berbasis Internet of Things

Agriculture or plantation in Indonesia is the main source of food needs. In agriculture or plantations, water is very important to meet the needs of plants. This research succeeded in making a tool that aims to help farmers to facilitate irrigation which can later be monitored. The system used in this research is automatic irrigation based on IoT (Internet of Things). The main components in this research are Arduino Mega Pro Mini, NodeMCU soil moisture capacitive, sensor DHT11 temperature sensor andsensor water level float. Other supporting components are DC Pump, Selenoid Valve, 20x4 LCD, Cooling fan,module stepdown LM2596, 2 relay channel and 12VDC adapter. The working system of this tool is to automatically fill the reservoir and then water it automatically using the parameters of the soil moisture sensor value and can be monitored from the data that has been obtained. The results showed that for the initial soil condition, the value from the sensor was 477 in conditions of watering until it stopped watering the soil showed damp at a value of 369. For the system, if the value was 400 indicated in dry conditions. and can do irrigation automatically and can also be monitored using a smartphone by using the application Blynk
