The current advancement of hydroponic technology is closely related to advances in automation technology such as the application of IoT. One of the hydroponic systems currently being developed is NFT hydroponics. This system has relatively easy monitoring of temperature, oxygen and nutrients. The purpose of this study was to determine the effectiveness of monitoring, temperature control and nutrition in the hydroponic NFT system. The system design produced in this study includes the use of Arduino Uno as a microcontroller connected to a DHT11 sensor for temperature monitoring, a pH 4502C sensor for monitoring nutrition, while an ultrasonic sensor monitors the level of nutrient water in the hydroponic system of pakcoy plants automatically. The use of pakcoy plants as samples of hydroponic plants with the NFT system is due to their relatively fast-growingvegetable. The results of the study showedthe use of the DHT11 sensor and the electrode sensor with the 4502C module as a nutritional monitoring unit has an accuracy of 98%. This shows that the monitoring and automation systems of the NFT hydroponic pakcoy are running well.
