DEVELOPMENT AND IMPLEMENTATION OF A MOBILE APPLICATION FOR THE MEASUREMENT OF TEMPERATURE AND RELATIVE HUMIDITY IN GREENHOUSE CROPS

Abstract

The tendency in recent years to improve worldwide agricultural production has opened the door to innovative research techniques to prevent diseases, pests, and negative consequences due to climate variations in crops. This study aims to develop an acquisition system using the embedded BeagleBone Black and the DHT 22 sensor, which allow measuring the physical parameters of temperature and relative humidity; these were registered in a database that was created in MySQL. The system was implemented within a greenhouse crop; additionally, a mobile application was developed, written in Kotlin language, to facilitate monitoring the physical parameters of temperature and relative humidity remotely, so that farmers can collect valuable information about their crops wherever they are. This development was carried out using a client-server structure, making use of free software and hardware, which makes for a low-cost, easily-implemented system for farmers. The monitoring system worked as expected, and the information obtained was reliable. The results show that the implementation is useful in greenhouse agriculture and that, through digital innovation, effective agricultural practices can be improved which could increase production and decrease costs, making use of modern technologies.
