To solve the problem of disturbing the existing heart rate and oxygen detector, a portable heart rate oximeter is proposed in this project. The device can detect and display the heart rate value and blood oxygen percentage of the human body at any time. The instrument gets rid of the burden of traditional medical devices, which greatly reduces the size of the instrument and is easier to carry. The heart rate oximeter designed in this project is smart and portable. It has a wide range of practical applications.
