Rancang Bangun Alat Pengingat Dehidrasi Menggunakan Sistem Mikrokontroller
Get PDFDehydration is a condition that can pose serious health risks, particularly if not detected and addressed promptly, with higher risks for vulnerable groups such as the elderly and children. This study aims to design and develop a dehydration detection device based on a color sensor using a microcontroller system that can monitor the body’s hydration status through urine color change analysis. The hardware design involves the TCS3200 color sensor to measure the intensity of urine color in three main parameters: Red (R), Green (G), and Blue (B), which are then processed by the microcontroller to determine the body’s hydration level. The testing was conducted with 24 urine samples of varying colors, representing hydration conditions ranging from normal to severely dehydrated. The test results show that as dehydration increases, the Red (R) value increases, while the Green (G) and Blue (B) values decrease. In the normal condition, Red values range from 130-145, Green from 170-210, and Blue from 205-210. In mild dehydration, Red is between 150-165, Green 110-130, Blue 130-160; in moderate dehydration: Red 171-186, Green 75-90, Blue 81-105; in severe dehydration: Red 195-205, Green and Blue below 50; in very severe dehydration: Red 217, with Green and Blue approaching 0. The average error percentage between the sensor and manual data was under 5%. The system provides voice notifications using the DFPlayer Mini corresponding to the detected hydration level
