Abstract:
Nowadays, automatic control has played a
vital role in advance of engineering and science.
The accurate real-time control system is essential
for non-stop running industries and production. In
this paper, Proportional Integral Derivative (PID)
based microcontroller is applied in the integrated
circuit to fill the liquid. Arduino, an open-source
electronic prototyping platform is used for this
system. It supports PID function to drive DC
motor by changing its voltage with Pulse Width
Modulation (PWM) signal. Ultrasonic sensor is
used to detect the liquid level. It can be filled both
level and amount of liquid according to the
desired input. By using Stepper Motor, the place
of the sensors and liquid-tap are reached at
necessary location. Proportional gain (Kp),
Integral gain (Ki) and Derivative gain (Kd) in PID
controller are calculated and compared for this
system. According to the experimentation, PID
Controller provides the effectiveness in
controlling thisliquid filling system
