AUTOMATIC HAND WASHING TOOL USING ULTASONIC SENSOR AND ARDUINO UNO CONTROLLER
According to World Health Organization (WHO), it is important to wash your hand at least for 20 seconds to ensure your hand free from germs and viruses. Oktania Hasna Sulistiyaningrum, a student of the Electrical Engineering Education Study Program of UNY decided to design an automatic hand washing device to make this activity easier. By using ultasonic sensor and an Arduino Uno controller, there is no need to push any button whenever people want to wash their hands.
