Implementation Of Message Queueing Telemetry Transport Protocol for Hydroponic Parameter Monitoring And Visual Hydroponic Greenhouse Based On Edge And Cloud Computing

A hydroponic system uses water as a medium to grow plants. One of the hydroponic techniques is drip. Hydroponics is very dependent on two elements of nutrient solution that affect plant growth, namely Total Dissolved Solids (TDS) and hydrogen ion potential (pH). Optimal growth occurs when TDS and pH are consistently balanced over time, ensuring plants get the nutrition they need when they need it. In this study, the monitoring system uses edge and cloud computing to access data offline and online. The MQTT protocol is used to send monitoring data from the Raspberry Pi to the server. The results show that the monitoring system can run under online and offline conditions. Besides, the average accuracy of the pH sensor is 99% and the average accuracy of the EC sensor is 96%. The results of the delay shows the potency to obtain average value category, in this study is 301.706 ms.
