3 Proposed Methodology

The prototype model system would consist of sensors and actuators which would be interfaced using STM Nucleo Mbed Board. Three sensors, namely the soil moisture sensor, light sensor, and the temperature sensor, are to be used to measure the greenhouse parameters. The corresponding actuators would trigger the irrigation system, lighting system, and the ventilation system, respectively. The ventilation system consists of fans and roof vents to provide circulation of air inside the greenhouse. These sensors measure the physical quantities, and they would be sent to the processor for processing, and depending upon the predetermined threshold, the actuators would be controlled through a power driver circuit. Additionally, the sensor values will be uploaded into the Tata server cloud in HEX format and as a JSON string. But to enable easy comprehension of data, this would be converted to decimal values. This makes it easier for the farmer to the monitor the greenhouse remotely. This data would be made available in the Microsoft Azure Cloud through a backend python script that will act as a bridge between the Tata server and the Azure Cloud. The data is thus stored in tables in the cloud. For visualization and analytics purpose, the user interface will be created using Microsoft Power BI which retrieves the data from the table storage in the Azure Cloud with aid of the dedicated account name and the key generated. The GUI created would enable the farmer to view the real-time data of the parameters in the greenhouse.
