Aplikasi Pembangkit PWM pada Mikrokontroler ATMega 8535 untuk Mengendalikan Suhu Pemanas Air (Heater)

Abstract

Having done design a water heater (heater) which temperature is controlled using PWM. As the central control of all devices designed to use a microcontroller ATmega8535. Also designed system equipped with an LM35 temperature sensor type that is used to detect any temperature changes that occur in the heater and the results will be displayed to the LCD. PWM is a method to generate repetitive output signal periods between the high and low. The signal is then controlled width in accordance with previously entered temperature value from the keypad. Observations show that the design of the PWM generator is functioning properly to control the temperature of the water heater
