    Low-cost proportional automatic control valve
    (Universidad Eafit, 2020) Arboleda Otero, Mariana; Builes Toro, Santiago
    Control and automation are the keys to escalate to industry 3.0, in a process the control valves are responsible for performing a corrective action in the process stream against a set point in the PID control loop, unfortunately its high cost does not allow the implementation of these equipment in academia and small industries. This project was based on the development of a functional prototype in hardware and software of a proportional valve for low-cost automatic control, coupling a conventional valve found in the market configured with microcontrollers, obtaining a low-cost device compared to those existing in the market that satisfy similar needs. The project was divided into four stages: i) mechanical coupling of the valve and the stepper motor, ii) electrical connection of the motor with the Arduino microcontroller, iii) programming the code to control the percentage of valve opening in direct relation with the number of steps of the motor, iv) transcription of the programming code to the Raspberry microcontroller to control the valve with the cell phone. A functional prototype with rapid response capacity was made and five buttons were set for the opening percentage of 0, 25, 50, 75, 100 %. In addition to this, it was possible to build a valve cell interface with a Raspberry microcontroller run through Google's mobile app, Home Assistant, to remotely control the valve.
