Development of an IoT-based Aquaponics Monitoring and Correction System with Temperature-Controlled Greenhouse

This paper presents a monitoring and automatic correction system for an aquaponics set-up in a temperature-controlled greenhouse using an Android device through Internet of Things (IoT). The system involves the acquiring of real time data detected by the light intensity sensor, and air temperature and humidity sensor. It also includes the monitoring of the pH level and temperature of the recirculating water of the system and the canopy area of the plant. If the acquired data is not within the threshold range, the correcting devices, namely grow lights, exhaust and inlet fans, evaporative cooler, aerator, and peristaltic buffer device were automatically triggered by the system to correct and achieve its normal status. The Internet remote access includes the effective wireless transmission and reception of data report between the system and an Android unit with the Android application in real-time.
