Rancang Bangun Soda Fountain Otomatis Menggunakan Smart Relay
(Politeknik Negeri Batam, 2014) Budiarto, Arif Wahyu; Istardi, Didi; Gozali, M.Syafei
Soda fountain system automatically uses the proximity sensor as a sensor to detect the height of a glass which then detected using fiber optic sensors to detect the presence of glass, this tool works by using a timer as a controller of the total volume of water flowing into the glass and use as tap water solenoid valve electrically. Systems of this tool using a smart relay by using three different size glasses high but the same diameter glass used between glass high, medium and small. The process of filling a small glass of water for the charging time is needed is 9 seconds, for glass was required charging time is 12 seconds and for a large glass of the required charging time is 18 seconds. Average error value in a small glass of water volume is 15.19% and the charging time error is 8.88%, while the glass was the average size of the error value is 5.04% water volume and water charging time error value is 3, 11% and testing for large size glass of water volume error value is 1% with water filling time error value is 0%.
