Cholesterol Checking Tool and Blood Type Prototype with Telegram Notification System.

The blood, which is divided into groups A, B, O, and AB, is a vital organ. Furthermore, the body needs cholesterol as a lipid, and the amount of cholesterol is a sign of health. A cholesterol level of 200–239 mg/dl is considered healthy. If it is very high, though, cholesterol can accumulate in the blood vessels and obstruct blood flow. This research built an Arduino Uno-based system to counterbalance the technical improvements in the use of LDR and Photodiode sensors that monitor blood type and cholesterol automatically without injections and send notifications to Telegram. This study sheds light on a significant advancement in medical sensor technology. The created device can check blood type and cholesterol levels with high accuracy and greater user convenience than prior technologies that required invasive procedures. The selection of LDR and photodiode sensors was based on their capacity to identify differences in blood samples and their sensitivity to light fluctuations. Medical teams can more effectively monitor patient symptoms thanks to the system's real-time notifications to the Telegram app. Programming and sensor integration are made flexible and simple by using an Arduino Uno in this setup. The primary conclusions of this study demonstrate that this technology can offer a useful non-invasive method for assessing one's health, increasing diagnostic precision and efficiency. The primary output of this research is the creation of a prototype for medical applications that integrates digital communication and sensor technologies, potentially lowering patient risks and expenses. Additionally, this finding opens the door for the advancement of non-invasive diagnostic tools that are more convenient and safer. [ABSTRACT FROM AUTHOR]
