Alat Ukur Ketebalan Digital Menggunakan Sensor Hc-Sr04 Berbasis Arduino Uno R3

Abstract

Water visibility detector is the one of instrument which is detect the water clearance with the voltage output. The design of this instrument using the arduino uno as the microcontroller and photo transistor as its sensing device. The testing of water visibility using the homogeny liquid and compare with turbidity meter. The test result indicates the voltages is getting higher when the water visibility is clear
