PENGATUR KECEPATAN MOTOR DC DENGAN SENSOR SUHU BERBASIS MIKROKONTROLER ATMEGA16
Abstract: A telecommunication
cabinet usually uses a Direct Current fan with a Direct Current motor (DC
motor) to make the cabinet temperature does not exceed the temperature that is allowed.
Using a DC motor has weaknesses because it always rotates in full speed
although the temperature in the cabinet gets down already. It causes
inefficiency of the power consumption and the DC motor’s lifetime is not long
enough.The prototype of DC motor speed controller controls the speed of a DC
motor with the temperature environment as its reference. This circuit is built
by a temperature sensor LM35, a microcontroller ATmega16 as the processor that
analizes the input from the temperature sensor and relays. This prototype is
equipped with a Liquid Crystal Display (LCD) to display the temperature of the cabinet
and the DC motor speed. After the prototype is assembled and tested, it is
known that the circuit controls a DC motor speed according to the changes of
the temperature that has been determined by the software program. The DC motor
stops rotating if the temperature sensor senses the temperature below the
minimum temperature level.
