Abstract
A biosensor unit is coupled to a user device and may communicate with the user device over a short range wireless or wired interface. The biosensor unit includes an optical sensor used to obtain an oxygen saturation level, a heart rate and a respiration rate of a user. The biosensor unit may also obtain a blood pressure and a temperature of the user using one or more other sensors. The biosensor unit transmits the obtained biosensor data to the user device using the short range interface.
