Abstract:
Agriculture is one of the most important economic sectors in the world. On the one hand, most of its importance resides in the food that is produced. On the other hand, this sector employs millions of people in the world both directly and indirectly. The introduction of Internet of Things (IoT) solutions for crop monitoring and management was the next step to improve the quality of the product, the quantity in the production, and to reduce the use of resources such as water. In this paper, a practical design of a WiFi-based Wireless Sensor Network (WSN) for citrus crop monitoring is presented. A mathematical model is obtained from the results of practical tests performed with low-cost devices for different height configurations of both the Access Point (AP) and the emitter according to the distance. The maximum coverage for the AP for each configuration is obtained as well. The results show the number of sensor nodes necessary to monitor the field according to its extension, and the
number of APs needed to provide coverage for all the nodes deployed on the citrus field for each configuration. This way, a tool for the design of WSNs to monitor citrus plots is provided.
