SISTEMA DE ADQUISICIÓN DE DATOS DE BAJO COSTO PARA UN INVERNADERO BASADO EN TECNOLOGÍA DE ACCESO LIBRE
Resumen
Resumen
En este trabajo se presenta un sistema de adquisición de datos desarrollado para un invernadero clásico cenital que se basa en el microcontrolador ESP826612E y la computadora de bolsillo Raspberry Pi 3, los cuales son plataformas de hardware libre. Los parámetros obtenidos son la temperatura y la humedad. En el método se incluye la integración de los componentes al sistema de adquisición de datos, en particular el sensor de temperatura y humedad (DHT11), el servidor (Mosquitto y Node-RED), utilizando los protocolos de comunicación inalámbrica (WiFi y MQTT). Los resultados muestran la factibilidad para utilizar un conjunto de dispositivos inalámbricos para la integración de un sistema donde se requiere procesar información de manera remota, en este caso un invernadero.

LOW COST DATA ACQUISITION SYSTEM FOR A GREENHOUSE BASED ON FREE ACCESS TECHNOLOGY
Abstract
A data acquisition system for a classical zenith greenhouse is developed in this paper. It is based on the ESP826612E microcontroller and the Raspberry Pi 3, which are open source hardware. The humidity and temperature are the parameters to acquire. The methodology includes the integration of some key components, such as the DHT11 sensor, the Mosquitto and Node-RED server, using the wireless communication protocols (WiFi and MQTT). The results show the possibility to use a set of wireless devices in order to process the information in a remote connection, in this case a greenhouse.
Keywords: Data acquisition, greenhouse, mosquitto, Node-RED, Raspberry Pi.
