Design of an Automatic Watering System for Hydroponic Plants Using IoT Based Solar Panels
Abstract
Hydroponics is a way of cultivating plants without soil but using water as a medium. Currently, agricultural land, especially in urban areas, is very difficult to find; therefore, planting using the hydroponic method is a solution. Hydroponic plant control is mostly done manually. To increase the efficiency of hydroponic planting, an automatic irrigation system control tool based on the Internet of Things (IoT) has been created. The equipment includes an EPS32 microcontroller, voltage and current sensors, TDS sensors, pH sensors, and 20 WP solar panels. The plant flow control system automatically and remotely uses the Blynk application, and the measurement results are displayed via a 4 × 20 LCD. This system is designed to control the pH and nutrient levels that hydroponic plants need to remain stable. If the TDS sensor measures the nutrient level < 1000 ppm, then the nutrient pump will be active, and if the nutrient level is > 1400 ppm, then the water pump will be active.
