Abstract
This chapter presents ongoing work in the development of a hydroponics monitoring system by using IoT technology. Hydroponics is a method of growing plants in water based nutrient rich solution system, instead of soil. By monitoring the parameters of the solution in parallel with the environmental parameters inside the greenhouse, farmers can increase the production while decreasing the need for manual labor. Multiple networked sensors can measure these parameters and send all the necessary information to an Internet of things (IoT) platform (i.e., Thingsboard) in order the farmer or agronomist to be able to control and adjust current operating conditions (e.g. environmental controls) and plan the nutrition schedule. Furthermore Machine Learning (ML) can be used, so the system will provide recommendations to agronomists. The novelty presented in our system is that data contributed by multiple farming sites can be used to improve the quality of predictions and recommendations for all parties involved.
