Pengembangan Alat Peraga Viskositas Berdasarkan Pengukuran Kecepatan Angular …

This study aims to analyze and examine the development of Viscosity Instruments based on angular speed, which is used for students to understand the viscosity concept. A rotation phototransistor sensor and a PT 100 temperature sensors were used to detect the rotation per minute (RPM) as well as the temperature variation processed by a microcontroller, which is then displayed on the LCD scr…
