hello everyone I am doing a project with Arduino.
my question is not about the programming but it is about which IR sensor I must use to detect if the blood vessels contain alcohol or not and more alcohol concentration causing more light reflection.
is the proper sensor here QRD1114 or I must change it???
I made much research about alcohol effects on the IR reflection and I knew that when alcohol existing, more reflection of the radiation will happen. but I didn't know yet which sensor can make this project completed as i want while I am using it with the Arduino UNO board
