Smart platform based on IoT and WSN for monitoring and control of a greenhouse in the context of precision agriculture

The rapid evolution of communication technology has spurred a revolution in many domains, which makes life more comfortable and convenient. In order to meet the surge in food demand due to the worldwide growing population, reduce farmers' efforts, and benefit from these technologies in agriculture, an intelligent platform based on IoT (Internet of Things) is proposed in this paper for monitoring and controlling greenhouse climate and irrigation. The system used a low-cost wireless sensors network (WSN) based on radio frequency (RF) communication for collecting and sending the greenhouse data (temperature, humidity, and soil moisture) to a processing unit based on Raspberry Pi. A fusion system based on fuzzy logic controller (FLC) was used to combine the collected data and to supply smart and optimal decisions to manage the internal climate and irrigation. The user can remotely monitor the greenhouse using a Human Machine Interface (HMI) developed under Node-RED server of IBM. In addition, the system allowed storing the environment data in a MySQL database to be exploited for control, monitoring, or history storage. The test results showed the effectiveness and success of the proposed platform.
