Abstract

We have developed a simple and low cost viscometer prototype by using laser. The prototype consists a laser with 405 nm as a light source, an LDR optical sensor as a detector, Arduino Uno as a signal processor and serial monitor as a display. We use frying oil as object. The frying oil was heated to obtain a certain viscosity because there are strong correlations between viscosity and temperature. The results show that when the temperature increase, the viscosity is decreased, and the output intensity detected by LDR will be increased. In this design the average error value is 36.89 centipoise compared to standard measurement using Ostwald viscometer. The main caused is the experiment was not done in the dark room as it should.
