The increased quality of life in recent times has led to a tremendous growth in research on IoT technology systems. This paper’s goal is to provide an IoT-based aquaponics system with monitoring capabilities that uses a NodeMCU ESP32 microcontroller board to enable remote control and Blynk application-based electrical device monitoring. In order to read and measure the pH value and the percentage of water level, this system used sensors such as pH and water level sensors. Hydroponic and aquaculture systems are combined to create the aquaponics system prototype. Air is used as a growth medium for plants in hydroponic gardening. Fish are raised or cultivated using an aquaculture system. With this novel technique, water is sent from the hydroponic system to the aquaculture, and air is returned to the hydroponic system from the aquaculture. Fish waste that is beneficial to plants can be found in aquaculture water.
