PROTOTYPE PINTU OTOMATIS MENGGUNAKAN SENSOR ULTRASONIK BERBASIS ARDUINO UNO

ABSTRACTThe development of automation systems continues to increaseevery year. One of them is the automation system on automaticdoors. The use of human power in opening and closing the roomdoor can be replaced with electronic devices. So the use ofminus power in opening and closing the door can be done usingthis device so that it is more efficient and effective. In makingthis Prototype using three main components namely UltrasonicSensor, Arduino Uno Microcontroller and Actuator in the form ofa servo motor. The ultrasonic sensor is used to detect thepresence of humans who are about to go to the door, the servomotor is used to open and close the door and the Microcontrollerfunctions to process signals from the ultrasonic sensor andprovide output signals to the actuator. From the results of eighttests In the entrance direction test there were two failures outof eight tests.Keywords: Automatic Door, Arduino Uno, Ultrasonic, ServoMotor
