Real-time Nutrient Film Technique Management and Monitoring System Using Internet of Thing
Publication Date : 17/06/2019
Nutrient Film Technique (NFT) is a modern cultivation system that introduced under a hydroponic system that suitable to apply in a small or large unit area. However, conventional NFT system requires plenty of time and workforce to manage and monitor the fertilizer solution. Therefore, there is a need to improve the existing conventional NFT management and monitoring technique in order to save time and reduce workforce. Thus, we built the NFT management and monitoring system that can be monitored and get the real-time data of the several fertilizers’ parameters based on the Internet of Thing (IoT) technology. The parameters such as electrical conductivity (EC), pH, temperature and water level were measured using sensors that connected to the Generic NanoFI microcontroller and Wi-Fi module ESP8266. Next, this system was calibrated to ensure the accuracy of data retrieved and sensitiveness of alarm systems. The result shows that this system was able to retrieve the real-time data of the fertilizer solution’ parameters and sending the early alarm notification if any data is exceeded the range setting. Thus, based on the calibration results, it is a reliable system to manage and monitor the NFT fertilizer solution remotely.
