Anemia is a medical condition with red blood cells or (Hb) amount less than 12g/dL.(Hb) Eamination usually done with invansive method, however this method has some deficiency, among them are lack of efficiency and not friendly for those that afraid with needle. This research is intend to make a device to detect hemoglobin inside the blood with non invasive method with infrared and photodioda as its sensor and some others electronic series as support. From the test of this module, the maximum deviation is 1 g / dl and at least 0.1 g / dl, and has a maximum error of 6.4% and a minimum of 0.8% and an average error of 0.1% this tool is eligible to use because the maximum deviation value is 1 g / dl and the tolerance of hemoglobin is 1 g / dl.
