| Summary: | Measurement of blood glucose is crucial for maintaining body condition, especially
for individuals with diabetes mellitus. One way to determine blood glucose level is by
conducting Benedict’s test, where sample solution is dissolved with Benedict’s
reagent, causing the solution to change color according to the glucose content.
However, color observation is still commonly done manually, meaning it is only
observed with naked eye. This can lead to human errors due to variation in color
perception among individuals and lack of consistency due to subjective measurements.
Measurement error can result in misdiagnosis. Therefore, a measuring instrument is
needed to provide accurate and consistent color measurement. As a solution, the author
designed a colorimeter capable of detecting the color of a droplet resulting from the
mixing process in the Digital Microfluid system. The system works by capturing image
of the sample passing through the constant light and then processing the image to
obtain the HSV values of the droplet. The system utilizes a Raspberry Pi Zero W
microprocessor, a Raspberry Pi Camera V2 digital camera, and an LCD touchscreen
as the user interface. The system is programmed using the OpenCV library in Python. |
