Desain Dan Analisis Alat Ukur Ketinggian Curah Hujan Menggunakan Micro SD (<i>Secure Digital</i>) Sebagai Media Penyimpanan

Abstract

It has been designed and realized a rain meter type weighing bucket, this device by raining volume grader type weighing bucket, utilizing timbangan's principle with spiral spring. potentiometer that is strung up on spiral spring axis have output as changed as interference which its point in proportion to length increase of system. Raining volume to be gotten by weighs rainwater mass with permanence water type mass as big as 1 kg / liter therefore water mass point already been weighed one par with appreciative volumed rainwater. Measurement and count result already been measured and is read on mikrokontroler will thru feature LCD 16x2 and is kept on micro sd . Data that is taken as big as 20 kb in the period of 1 downloading hours. Quick its slowing inlay on penampung's container regarded by rain Intensity. gotten by measurement deviation (Deviation default) as big as 0,4 until 0,44 liters. With raining average that is taken up to 1 hour is 0.5 liter or one par with 0.5 kg water mass.
