dc.description.abstract | Oils have different compatibility within a heavy equipment and affect
machine performance. Therefore, an oil type identification tool has been
developed in this study using a light dependent resistor (LDR) sensor. The oil
used as the object of testing is under the Caltex brand with types SAE 10,
SAE 30, SAE 40, SAE 90, and SAE 140 with viscosity values of 6.0 cSt, 11.7
cSt, 13.7 cSt, 14.2 cSt, and 25.5 cSt respectively. The test is carried out by
placing an oil sample between the light source and the LDR sensor. The
intensity of light received by the sensor is strongly influenced by the
brightness of the color of the oil sample used. The analog value from the
sensor is then acquired by the Arduino Nano microcontroller for further
processing. The test results show that the designed tool has worked well and
able to recognize the type of oil with an accuracy rate of 96.7%. | en_US |
