Design And Implementation Of An Automation System For A Nutrition Pump In Hydroponics Using Arduino Uno

In this era of technology, the use of technology is growing rapidly. This can also be applied to agricultural systems, one of which is the hydroponic system. In this study, researchers developed a tool using experimental methods and data testing in the form of making a design and implementation of an automation system for a nutrition pump in hydroponics using Arduino Uno as microcontroller which can be accessed via internet. By utilizing several sensors such as TDS sensors, waterfloat sensors, DHT21 sensors, and DS18B20 temperature sensors which are processed for the purpose of displaying data such as temperature, temperature, water limit and total PPM (Part Per Million) values in hydroponic installations. In the automation system there is also a 12 volt dosing pump, which is used to drain the nutrient solution into the hydroponic system automatically. The focus of this research is on the application of the TDS sensor which functions as a trigger for the movement of the nutrient pump through the sensor readings contained in the water reservoir. To find out the direct data parameters, an automatic data storage system is needed or known as a data logger. In the data logger system, the RTC DS3231 module is used as a time saver. The automation system utilizes the Internet of Thing (IoT) which can be accessed via a smartphone using the Blynk application using the NodeMCU ESP 8266. The distribution of nutrients is carried out semi-automatically. In testing the data on the pump, there is an average delay of 7.43 seconds when sending data
