COMPARATIVE TEMPERATURE MEASUREMENT SYSTEM USING MICROCONTROLLER

Nowadays, people use automatic system toreduce their energy and time. The application ofcomparative temperature measurement systemisusing the mechanism of PID (proportionalintegral derivative) controller.The aim of thissystem is to automatically control the temperatureof water in PID control system and control the DCmotor pump speed with PWM. Controlling thePWM duty cycleisequivalent to controlling themotor terminal voltage, which in turn adjustsdirectly the motor speed. The purpose is tofacilitate heating system of a specifiedtemperature and to retain it at that temperature ina control manner. This system presents the lowcost and flexible system for controlling the watertemperature.The Arduino, one of the best ways forprecision control with low cost, easy to use andcompactible with open source operating system, isused as a microcontroller in this system
