RANCANG BANGUN PENYIRAM TANAMAN OTOMATIS MENGGUNAKAN SENSOR MOISTURE YL-39 BERBASIS ARDUINO UNO

Abstract

Developments in this era are increasing, humans expect a tool or technology that can help human work, so that technology becomes a necessity for humans. This tool aims to replace manual work to be automated. The benefit of this tool is that it can facilitate human work in watering plants. This tool uses a soil moisture sensor that functions as a soil moisture detector and sends commands to Arduino uno to turn on the relay driver so that the pump can flush water according to the needs of the soil automatically. Making this final project is done by designing, manufacturing and implementing system components which include Arduino uno as a controller, relay driver to turn the water pump on and off, LCD (Liquid Cristal Display) to display soil moisture values. From the results of the tests carried out, it can be concluded that the system will be active if the soil conditions are dry or the percentage of soil conditions is around 0-35%. The system will be deactivated when the soil has been wet with water or the percentage of the soil condition is at 35-100%.
