Study and Fabrication of A Small-Scale Hydroponic System with IOT Monitoring

Abstrak

This project presents the study and fabrication of a small-scale hydroponic system enhanced with Internet of Things (IoT) monitoring. Recognizing the critical role of agriculture in the developing of nations, this system addresses global challenges such as increasing food demand and the need for sustainable farming methods. Hydroponics, defined as growing plants in nutrient-rich water without soil, offers an innovative solution. This project utilizes a flood and drain hydroponic design, implemented using an ESP8266-based board as the main controller. The system communicates with various sensors, including pH, Total Dissolved Solids (TDS), and temperature sensors, and displays data on an LCD screen. An app called Blynk is employed for remote monitoring via smartphones. A Bell siphon device is also incorporated to regulate water flow within the system. In this IOT application, the Arduino collects data from sensors to send to the Internet and receives commands to control motors and actuators. The data collected from sensors is analyzed to evaluate system performance and efficiency. The pH and temperature of the water are maintained within the ranges of 6 to 7 and 25°C to 30°C, respectively, with nutrient levels between 1000 ppm 1400 ppm. The water flow rate to the grow bed is approximately 0.0295 litres per second. This hydroponic system conserves water and fertilizers while enhancing crop yields, demonstrating a promising approach to sustainable agriculture.
