Sensor selection and hydroponic saffron cultivation

IoT and sensors play an important role in optimizing the artificial cultivation of crops. The selection of sensors is important in order to ensure better quality and yield in an automated artificial environment. There are many challenges involved in selecting sensors due to the highly competitive market. This paper provides a novel approach to sensor selection for saffron cultivation in an IoT-based environment.

The crop used in this study is saffron due to the reason that much less research has been conducted on its hydroponic cultivation using sensors and its huge economic impact. A detailed hardware-based framework, the growth cycle of the crop, along with all the sensors and the block layout used for saffron cultivation in a hydroponic medium, are provided. The important parameters for a hydroponic medium, such as the concentration of nutrients and flow rate required, are discussed in detail. This paper is the first of its kind to explain the sensor configurations, performance metrics, and sensor-based saffron cultivation model.

The paper discusses different metrics related to the selection, use, and role of sensors in different IoT-based saffron cultivation practices. A smart hydroponic setup for saffron cultivation is proposed. The results of the model are evaluated using the AquaCrop simulator. The simulator is used to evaluate the value of performance metrics such as yield, harvest index, water productivity, and biomass. The values obtained to provide better results as compared to natural cultivation.
