The principle of the Sensor rely on the property of spectrum which collect data from hemoglobin and oxyhemoglobin in glow area and area of approximate infrared source and apply the formular “Lamnert Beer” to establish the evaluating equation. In fact, the basic calculating technique is to combine electro-photo SPO2 detecting technology with recording mock pulse rate technology to get the result, the process demonstrate as below:

Firstly, use glow with wavelength of 660 nm and approximate infrared with wavelength of 905 nm to put light on the finger tip ready to read analogue data.

Secondly, to process the data by electric circuit and microprocessor, then convey the data to LED display for reading.
