Design of a monitoring and control system for Aquaponics based on Iot technology

Abstract

This paper presents the design of environmental monitoring and control system in aquaponics based on Internet of Things (IoT) technology. This system allows users to monitor and control the operation of devices through the application on smartphones, including: 3 water pumps, 3 air pumps, pH sensor, dissolved oxygen (DO) sensor, temperature sensor and humidity sensor, exhaust fan and misting. These devices are monitored and controlled in two modes: automatic and manual control. For 3 pumps and 3 air pumps, in automatic mode, allows the user to set the pump time between water pumps and between air pumps. In manual control mode, allows the user to control water pumps and air pumps by the push of a button on a smartphone application. Monitor pH, DO and allows the user to set the pH threshold and DO threshold to give an alert when the pH and DO exceed the threshold. Monitor the parameters of temperature, humidity in the membrane house and allow setting the temperature threshold and humidity threshold to control the exhaust fan and misting respectively when the temperature and humidity exceed the threshold. This system tested at aquaponics farm - Dong Thap Aqua. The results show that this system is working reliably and promising which brings significantly benefits to aquaponics. Besides, it also contributes to improve production efficiency and sustainable development of green agriculture.
