Agricultura de precisión mediante WSN con nodos inteligentes aplicada a un sistema de riego en cultivo de mora.

Abstract

The network of intelligent sensors for the supervision and control of irrigation of the blackberry plot at the ESPOCH Experimental Irrigation Center (CER) consists of a electronic system of wireless sensors based on Arduino development boards. The system is based on three nodes with a mesh-type network topology that allow the measurement of soil moisture and ambient temperature to suggest when it is necessary to carry out the irrigation and its volume. In addition, it includes a mobile application that maintains communication via Bluetooth to display the readings of the sensor node. On the other hand, the data is received and displayed in real time in a way graphically and stored on the free platform ThingSpeak. The acquisition of the samples was carried out during eight consecutive days and the results presented show that the implemented wireless system maintains communication without loss at distances of 300 meters in direct line of sight with a reception power of -58 dBm.
