Do you know how much oxygen you have in your blood? You may not be worried about knowing since you’re alive and thus can infer you have enough. But, visiting high altitudes can be made safer, and implementing a new workout regimen can be made more effective, with an oximeter.
These devices can be pricey and offer little to no customization. So, the people at SmartMaker decided to make an oximeter following the open-source model to achieve low cost and an endless potential for modification.
The resulting device -- the SmartPulse -- is a working prototype that is low power, and has an embedded microcontroller for creating the necessary spectrometry wavelengths, reading data, calculating parameters, and generating the output. It includes a Bluetooth 4.0 interface that makes it very simple to link the device to a plethora of others. The SmartPulse can run on two AAA batteries or on 3.7V Li-ion batteries.
