Implementation of and agriculture 4.0 oriented system for monitoring environmental variables: Alstroemeria hybrida - Astromelia case

In recent times, agriculture faces new challenges due to climate change, water scarcity and the need to increase crop productivity, agriculture 4.0, through the application of technology allows real-time monitoring of environmental variables in crops such as astromelia, becoming a valuable tool for decision making of small farmers. This study implements a proposal oriented to agriculture 4.0 with the deployment of Wireless Sensor Network (WSN) by making use of the ESP32 module, accompanied by soil moisture sensors YL-69, temperature and relative humidity DHT11 and rain sensor HL-83, for data acquisition, which will then be transmitted via a Wi-Fi connection to a MySQL database on a web server implemented for this purpose, allowing real-time monitoring through a web application developed using PHP, Javascript, HTML5, CSS, Jquery and Google Charts.The implementation of our proposal in a Phytotoldo dedicated to the cultivation of Astromelias, which allows to confirm the suitability of ESP32 modules and their associated sensors for real-time monitoring of environmental variables in the cultivation of Astromelias, and the correct recording of historical data for later evaluation to remain easily adaptable for other crop varieties.
