Blood Group detection -- 2

Determination of blood groups of a human being is a vital factor. Man by nature has any one of the blood groups namely A, B, AB and O. The blood group “AB” is called the “Universal acceptor” and the people with the “O” group are called “Universal donors”. During blood transfusion any mismatch can lead to the death of a person. Hence it is of utmost importance for every person to identify his/her blood group. Blood grouping done so far is a manual process. As far as hospitals and blood banks are concerned, a number of blood samples have to be identified with in a short span of time. The manual process is a laborious and time-consuming one. Hence we have to device a new instrument cum method which eliminates all types of problems associated with conventional methods. The better choice is IR Sensor. IR Sensor is a very important constituent of modern technology.
