Abstract:
Nowadays, people use automatic system to
reduce their energy and time. The application of
comparative temperature measurement systemis
using the mechanism of PID (proportional
integral derivative) controller.The aim of this
system is to automatically control the temperature
of water in PID control system and control the DC
motor pump speed with PWM. Controlling the
PWM duty cycleisequivalent to controlling the
motor terminal voltage, which in turn adjusts
directly the motor speed. The purpose is to
facilitate heating system of a specified
temperature and to retain it at that temperature in
a control manner. This system presents the low
cost and flexible system for controlling the water
temperature.The Arduino, one of the best ways for
precision control with low cost, easy to use and
compactible with open source operating system, is
used as a microcontroller in this system.
