Diseño e implementación de un prototipo dosificador mediante el control de bombas peristálticas por modulación por ancho de pulso para la preparación de bebidas funcionales.

Abstract

The present Project is born from the lack of DOSING SYSTEMS who helps to avoid liquid losses thanks to DOSING PUMPS precision. Dosing pumps are used on the development of FUNCTIONAL BEVERAGES, that could help to improve the quality of life or some physiological need of the consumer. Furthermore, this work has a wide range of industrial applications as chemical combinations, as well as fertilizer combinations. In order to begin with the dosing process, the HMI (Human-Machine Interface) is used to allow the user to choose their functional beverage of preference. Then the signal is received and processed by the MICROCONTROLLER Atmega 2560 from the Arduino. Afterwards, the microcontroller sends the PULSE WIDTH MODULATION (PWM) signal that will enable the dosing through the PERISTALTIC PUMPS of the chosen beverage. The coding for the system is done in ARDUINO IDE for the microcontroller and NEXTION EDITOR for the development of the Human-Machine interface. In addition, the serial communication allows data transmission between Nextion’s touch screen and Arduino, in order to run the coding commands and to activate the peristalt ic pumps according to the product request.
