Monitoring of Smart Greenhouse Using Internet of Things (IoT)

Greenhouse is the place where the plants are grown in a controlled manner. Monitoring the greenhouse environment is necessary to maintain the optimal conditions for plant growth. Using wireless sensor networks, the monitoring of the greenhouse environment can be not only simplified but can also contribute to increase in the production efficiency. Monitoring and control sensors are used for different purposes in agriculture. Smart greenhouse farming using Internet of Things (IoT) are deployed in rural area to benefit the farmers by automatic monitoring and controlling the plant environment. Thus, IoT devices and technologies are deployed in smart greenhouse that mainly focused on enhancing greenhouse farming's effectiveness and efficiency. The proposed system uses various IoT devices for automatically monitoring the parameters that affect plant growth, such as temperature, humidity, soil moisture, water pH and to perform particular actions like turning on the irrigation based on the threshold parameters that are set. The measured parameters are transmitted via GSM (Global System for Mobile communication) module to the ThingSpeak IoT cloud platform where the data is stored. These stored data are displayed and analyzed using ThingSpeak's built-in MATLAB features. In addition, the system incorporates the plant disease detection using image processing techniques, which is crucial for early detection and prevention of crop loss. A website has been developed where all the parameters, which are measured, are displayed and analysis performed in ThingSpeak cloud can be seen by the user.
