Design of a Prototype Device for Measuring Electricity Consumption and Water Density for Hydroponic Plants Based on IoT

Abstract

One of the problems with hydroponics is that the electrical power consumption and nutrient levels that have been used are not monitored. The monitoring carried out in this research was to determine real-time electrical energy consumption and nutrient levels. The method used is experimental with a design method using a prototype. The system uses eight water pumps with measurement results of 236 W power, 2 A current and 219 V voltage. The load (water pump) in the hydroponics is active for 24 hours, the electrical energy consumption in the hydroponics is 5.66 kWh/day. The cost of using electricity for 24 hours is IDR 8,182.78 if 30 days is IDR 245,483.00. The nutrient level in hydroponics with a capacity of 130 liters and a nutrient mixture of 1.2 liters is 363 PPM, and at a capacity of 100 liters with a nutrient mixture of 1 liter it reaches 495 PPM. The designed measuring instrument functions well.
