IMPLANTACIÓN DE UNA LPWAN PARA MONITOREO DE TEMPERATURA Y HUMEDAD EN UN INVERNADERO
Resumen
Resumen
Se presenta la implantación de una LPWAN conectada a la Internet para monitoreo de temperatura y humedad de un invernadero. La LPWAN está formada por cinco nodos distribuidos en el invernadero y un gateway conectado a la Internet. Es una solución de IoT, donde cada nodo consta de un microcontrolador, un sensor de temperatura ambiente y humedad relativa y un transceptor de radio LoRa. Periódicamente los nodos envían la información recabada por los sensores al gateway y éste a su vez la transmite a un servidor ubicado en la nube. Operando una interfaz de usuario, se puede acceder al servidor y monitorear los valores de temperatura y humedad enviados por los nodos. La interfaz de usuario puede acceder información de diferentes invernaderos en los que exista una LPWAN como la diseñada en este trabajo. El alcance de la LPWAN fue de 12.5 Kilómetros con línea de vista.
Palabras Claves: Gateway, IoT, LoRa, LPWAN, sensor de temperatura.
IMPLEMENTATION OF A LPWAN FOR TEMPERATURE AND MOISTURE MONITORING IN A GREENHOUSE
Abstract
This paper presents the implementation of a LPWAN connected to the Internet to monitor the temperature and humidity of a greenhouse. The LPWAN consists of five nodes distributed in the greenhouse and a gateway connected to the Internet. It is an IoT solution, where each node consists of a microcontroller, an ambient temperature and relative humidity sensor and a LoRa radio transceiver. Periodically the nodes send the information collected by the sensors to the gateway and this in turn transmits it to a server located in the cloud. By operating a user interface, you can access the server and monitor the temperature and humidity values sent by the nodes. The user interface can access information from different greenhouses in which there is an LPWAN as the one designed in this work. The scope of the LPWAN was 12.5 Kilometers with line of sight.
Keywords: Gateway, IoT, LoRa, LPWAN, temperature sensor, transceiver.
