Survelliance of Hydroponics System Using MQTT App

Hydroponic pots are being used to manage agriculture in the most effective way. Hydroponics is a model of advancement in agriculture. When a farmer uses an effective hydroponic system, plants produce thirty to forty percent more than they would under conventional agriculture. We have created a hydroponic system using the Nutrient Film Technology (NFT) and used a more sophisticated IOT network that allows anyone, anywhere, at any time to use a smartphone to monitor an NFT hydroponic system. Hydroponic system characteristics including temperature, humidity, water level, water quality, and soil moisture are collected using an ESP32 microcontroller. Here, we used the Message Queuing Telemetry Transport (MQTT) App to show the hydroponic system sensor information. To send and receive messages, a MQTT-enabled mobile app uses a MQTT library. Utilizing the MQTT Protocol, all acquired sensor data is sent to the MQTT App, where the values are also shown on an LCD.
