1. A monitoring apparatus, comprising:

  • a housing configured to be attached to a body of a subject; and

    a sensor module disposed within the housing, the sensor module comprising;

    an energy emitter that directs modulated energy at a target region of the subject;

    a detector that detects an energy response signal from the subject, wherein the energy response signal is associated with a physiological condition of the subject;

    a filter that attenuates time-varying environmental interference from the energy response signal, wherein the time-varying environmental interference is caused by one or more of the following;

    sunlight, ambient light, airflow, and temperature; and

    at least one processor that controls operations of the energy emitter, detector, and/or filter.
