<![CDATA[Invasive methods used in glucometers, which require blood samples through needle pricks, often cause discomfort, making many patients reluctant to monitor their blood glucose regularly. This study developed non-invasive blood glucose monitoring technology using the MAX30102 sensor, which employs the photoplethysmography method with a near-infrared wavelength of 880 nm. Blood glucose levels were estimated based on the range in maximum and minimum infrared intensity values (RMM Amplitude), processed using a linear regression equation derived from a dataset of 20 respondents. Testing was conducted by comparing the prototype results with the EasyTouch glucometer, standardized by the Indonesian Ministry of Health. The results showed a positive correlation between RMM Amplitude and glucometer readings, with the device achieving an accuracy of 88,7% for blood glucose levels below 120 mg/dL. The supporting application successfully displayed data in graphical form, provided notifications, and offered recommendations when blood glucose levels were outside the normal range.
