Technology has transformed the practice of medicine and surgery in particular over the last several decades. This change in practice has allowed diagnostic and therapeutic test to be performed less invasive. In this project, we propose a non-invasive approach to Hemoglobin measurement using sensor and arduino. The method in this project involves both hardware and software. The Hemoglobin is measured at the tip of any fingers, a Power LED and IR and RED LED sensor are used as a light source. This light source is detected by the photo detector and data is collected through Arduino and shows the output in LCD display. For the non-invasive Hemoglobin measurement, the hardware part has been used. This Hemoglobin measurement is ruling the investigation out of diseases. The invasive method is an expensive process as it involves the reagents for both the hospital and patients. It is also a risk to takethe blood samples from theweak patients. Real time monitoring and infection free operation can be achieved through non- invasive method. This device could be effectively used by the physicians, and the patients for the implications of noninvasive Hemoglobin technology particularly in trauma.

The major building blocks of this project are:

• Power supply.
• Arduino UNO.
• IR and RED LED sensor.
• LCD display.

  Software’s used:

• ARDUINO IDE.
• Embedded c language.
