Therefore, there is a high demand for interconnection in any processes made by industries, companies even at home, which have a need to monitor different sensor networks in order to simplify remote manipulation, with low power consumption and low operating costs. This research presents the design and implementation of a prototype that improves the scope of the Xbee s2c device, with the creation of a radiant system that operates in the 2.4 GHz band. The system consists of an array of microstrip antennas, a Hairpin filter and an RF amplifier, which monitor environmental sensors within a network. An array of 2x2 Patch antennas is designed with a gain of 23.06 dBm. Then the Hairpin filter design was designed, which were created with Ansys HFSS and AWR Design demo tools, respectively. The prototype consists of 2 environmental sensors (temperature and humidity) which are controlled by an Arduino Pro mini card that is responsible for sending the data of these sensors. Subsequently, the information is sent via the Xbee s2c device to another device with the same characteristics, configured transparently, that is, as a transmitter and receiver. Data collection was implemented with an ethernet module that at the time of obtaining them, it sends them to a platform where they will be monitored and refreshed every 3s, it was stablished that an IP address will be used in the programming of the receiver to enter the website, taking into account that is working within a LAN network. The tests were carried out in 4 scenarios, two of them from the National University of Chimborazo, using both the factory antennas of the Xbee and the radiant system designed for data transmission tests, which are analyzed in the DIGI XCTU software to verify the signal strength indicator received by the system (RSSI) at different distances. As a result, the elaborate radiant system allows to improve the range |
