RANCANG BANGUN ALAT PENDETEKSI GOLONGAN DARAH DAN SATURASI OKSIGEN BERBASIS ARDUINO UNO

In this study a device was designed to detect human blood group using the ABO method which is integrated with oxygen saturation meter. This tool can agglutination or non-agglutination reactions in samples that have been treated antisera and will then be read by three TCRT5000 sensors are reflective used as detectors of A, B Rhesus antigens when occur on paper. sample test. addition, MAX30100 sensor also measure body. Data has directly processed Arduino Uno results from reading displayed 16x2 LCD. testing detector where all tests respondent's totaling 8 obtained success value 100%. Oxygen Saturation Measuring Instrument an accuracy 99.53%.
