ams OSRAM SFH 2703 - CHIPLED® broadband silicon PIN photodiode

Along with the "Quantified Self Movement" gaining popularity, there is an increasing interest in medical measurement methods that can be integrated into so-called wearable gadgets such as watches, smart phones, or fitness bracelets. Optical sensors like the SFH 2703 expand the possibilities of self-observation, as they also offer a straightforward measurement of the heart rate and oxygen saturation of the blood.
