1. A portable biometric monitoring device comprising:

  • housing having a physical size and shape that is adapted to couple to the body of the user;

    at least one band, coupled to the housing, to secure the portable biometric monitoring device to the user;

    a physiological sensor, disposed in the housing, to generate data which is representative of a physiological condition of the user data, the physiological sensor including;

    a first light source, disposed in the housing, to generate and output light having at least a first wavelength, anda photodetector, disposed in the housing, to detect scattered light;

    a first light pipe, disposed in the housing and optically coupled to the first light source, to direct or transmit light from the first light source along a predetermined path to an outer surface of the housing; and

    processing circuitry, disposed in the housing, to calculate a heart rate of the user using data which is representative of the scattered light.
