Sistema de control para el balance de PH y monitoreo remoto de temperatura y nivel de solución en un cultivo hidropónico de fresas

Abstract

Being of utmost importance to have a balanced pH for a hydroponic strawberry crop, a prototype was designed by means of an ESP32 microcontroller, which controls the pH of the crop by means of solenoid valves. When the sensor shows that the pH of the solution is unbalanced, one of the electrovalves containing either the acidic or basic solution will be activated, depending on the case. After this, the balanced solution will be sent to the crop. On the other hand, data are also obtained on the temperature of both the solution and the environment, humidity of the environment and the level of the solution. If the level of the solution is low, an audible alarm will be activated with an active buzzer and subsequently an electrovalve will be activated, which will maintain the adequate level of the solution for the crop. Finally, a prototype was obtained by means of which the pH level is balanced to maintain a good absorption of nutrients in the hydroponic cultivation of strawberries, with data acquisition of the environment, such as: humidity and temperature and as for the solution: pH, temperature and level of solution in which the crop is. The data acquisition can be visualized by means of a TFT screen and a visualization through the ThingSpeak platform, which enables remote monitoring of the hydroponic strawberry crop.
