Design of Human Blood Type Detection Monitoring Device Based On Arduino Microcontroller

Abstract

The design of a monitoring tool to detect human blood type based on an Arduino micro-controller that will be displayed on Android is designed to automatically determine blood types A, B, AB and O and will be displayed via LCD and Android. This tool is designed considering the current rampant Covid-19 in Indonesia. Therefore, many patients need blood donors and do blood tests. So this tool is used effectively so that the medical team and donors do not have difficulty in conducting blood type tests or in carrying out blood transfusions. Knowing the properties of the human blood type detector is the purpose of this study. Blood types are identified using the blood type detector agglutination process, which occurs after the blood sample is dripped with "anti-sera" or antigens A, B, AB and Rh. This blood sample is then placed on a glass slide above the LDR. The micro-controller, which has been programmed to distinguish blood types, receives the data after that. A 16x2 LCD is used to display the results of the micro-controller after the database is activated and sent to the Android device.
