Telah dirancang suatu sistem keran dispenser otomatis berbasis mikrokontroler AT89S52. Pada sistem ini, keran akan terbuka ketika cahaya dari LED ke fotodioda (yang terpisah sejauh 16 cm) terhalang oleh cangkir atau tangan. Air akan mengalir ke dalam cangkir melalui keran dan berhenti secara otomatis ketika jarak antara sensor ultrasonik dan permukaan air mencapai 5 cm. Sinyal keluaran mikrokontroler akan naik turun sebelum mencapai jarak tersebut. Hal ini terjadi karena pengaruh dari permukaan bidang pantul yang beriak pada saat air bergerak ke atas.Downloads
