Abstract

A vortex mixer can be utilized for repetitive sample-mixing tasks that need execution over a predetermined period. The subject of this study is a device known as a vortex mixer, which is used to rapidly homogenize liquids in a compact container. The module's design aims to produce a portable vortex mixer with an object detector for use in the solution-mixing process. The module comprises a circuit controlled by ESP32, an infrared sensor for object detection, and a TFT LCD ILI9341 for display. A charging battery can also charge this device, making it easier to transport. This instrument has three degrees of speed: the low-level ranges from 300 to 500 RPM, the medium level ranges from 600 to 1500 RPM, and the high level extends from 1600 to 2500 RPM. The results reveal that the motor speed accuracy of the vortex mixers is low at 95.78%, medium at 97.49%, and high at 99.19%. Moreover, the battery life is lengthy, with an average charging time of 2.62 hours and a discharging time of 9.7 hours for 300 RPM; 7.34 hours for 600 RPM; and 3.03 hours for 1600 RPM, respectively.

Abstract

Diabetes is a chronic metabolic disorder caused by a decrease in the pancreas to produce insulin. We present a medical records system and reminders to patients of the measurement results of non-invasive blood glucose levels. Measuring blood glucose levels is vital in avoiding potential adverse health effects like diabetes. Generally, measuring blood glucose levels using the conventional method is injure the patient's finger. Currently, the non-invasive method was famous as one of the detections of blood glucose by applying the physical properties of laser absorption. In this paper, we use the photodiode as a detector, the LED as a sensor, and a signal conditioning circuit. The results showed that non-invasive glucose monitoring has the potential to measure glucose levels with sensitivity and linearity of 3.21 mg/dL and 98%, respectively. As a result of measuring the blood glucose levels of the subject was displayed on the LCD module was designed. We designed a simple application and medical record using Blynk applications and GUI MATLAB for recording the measurement results of blood glucose level. In the future, applications that have been developed can be used by doctors for monitoring the measurement of the blood glucose level and provide information to patients by mobile applications, sending an email or message the measurement results, the decision of a disease or not, and reminds the re-measurement time
