1. A method of measuring one or more conditions within a predetermined area comprising:
receiving at a control system a signal including scattered light and time of flight information associated with a plurality of nodes of a detection system;
parsing the time of flight information into zones of the detection system;
identifying one or more features within the scattered light signal; and
analyzing the one or more features within the scattered light signal to determine a presence of the one or more conditions within the predetermined area.
