A system and method includes a master/slave data bus, a plurality of sensing nodes, and a master node configured to communicate with the plurality of sensing nodes over the master/slave data bus. The master node is configured to command the plurality of sensing nodes into an event monitoring mode over the master/slave data bus. The plurality of sensing nodes are configured to digitize and retain a first amount of data during a listening mode of the event monitoring mode and detect an event based upon the first amount of data. The plurality of sensing nodes are further configured to drive an event trigger on the master/slave data bus upon detection of the event, and digitize and retain a second amount of data following detection of the event trigger on the master/slave data bus.

1. A method of collecting data in a system that includes a master controller and a plurality of slave sensors connected to communicate digital data via a master/slave data bus, the method comprising: commanding, by the master controller over the master/slave data bus, the plurality of slave sensors to enter an event monitoring state, wherein each of the plurality of slave sensors enter a listening mode;sensing, by the plurality of slave sensors, characteristics of an environment as first sensed data;digitizing and retaining, by the plurality of slave sensors, the first sensed data during the listening mode;detecting, by a first one of the plurality of slave sensors, a detected event based upon the first sensed data;driving, by the first one of the plurality of slave sensors in response to the detected event, an event trigger on the master/slave data bus, wherein the event trigger is a known logic state or pattern on the master/slave data bus;detecting, by the plurality of slave sensors, the event trigger on the master/slave data bus;sensing, by the plurality of slave sensors, the characteristics of the environment as second sensed data;recording, by the plurality of slave sensors, the second sensed data as event data in response to detection of the event trigger on the master/slave data bus; andreturning, by the first one of the plurality of slave sensors, to the listening mode following recording event data, unless a duration associated with the event monitoring state has expired or the master controller has commanded the first one of the plurality of slave sensors to exit the event monitoring state. 2. The method of claim 1, further comprising: monitoring, by the master controller, the master/slave data bus for the event trigger; andrecording, by the master controller, an event time, wherein the event time is based upon a system time or a duration from a start of entering the event monitoring state. 3. The method of claim 1, further comprising: recording, by the first one of the plurality of slave sensors, the detected event and an event detection time associated with the event data based on a system definition of time or a duration from a start of the event monitoring mode. 4. The method of claim 3, further comprising: correlating, by the master controller, the event data from the plurality of slave sensors using the event detection time. 5. The method of claim 1, further comprising: extracting, by the master controller, individual features regarding the detected event utilizing the event data from the plurality of slave sensors. 6. The method of claim 1, further comprising: processing, by the plurality of slave sensors, the event data as processed data; andproviding, by the plurality of slave sensors, the processed data to the master controller. 7. The method of claim 1, further comprising: determining, by the master controller, that the first one of the plurality of slave sensors detected the detected event based upon an event type of the detected event. 8. A method of collecting data using a plurality of sensors connected to a digital master/slave data bus during an event monitoring mode, wherein the method comprises: commanding, by a host controller over the master/slave data bus, the plurality of sensors into a listening mode;collecting, by the plurality of sensors, first sensed data, wherein the plurality of sensors digitize and retain the first sensed data;detecting, by a first one of the plurality sensors, an occurrence of a first event based upon the first sensed data;driving, by the first one of the plurality of sensors, the master/slave bus with an event trigger, wherein the event trigger is a known logic state or pattern on the master/slave data bus;identifying, by the host controller, that the first one of the plurality of sensors detected the event upon detecting the event trigger on the master/slave data bus;instructing, by the host controller over the master/slave data bus, the plurality of sensors, to retain an amount of the first sensed data and record second sensed data as event data; andreturning, by the first one of the plurality of sensors, to the listening mode following recording event data, unless a duration associated with the listening mode has expired or the host controller has commanded the first one of the plurality of sensors to exit the listening mode. 9. The method of claim 8, further comprising: detecting, by a second one of the plurality of sensors, a second event; anddriving, by the second one of the plurality of sensors, the event trigger. 10. The method of claim 8, further comprising: detecting, by a second one of the plurality of sensors, the event trigger; andrecording, by the second one of the plurality of sensors, an event detection time associated with the event trigger. 11. The method of claim 8, further comprising: recording, by the first one of the plurality of sensors, the detected event and an event detection time associated with the event data based on a system definition of time or a duration from a start of the event monitoring mode. 12. The method of claim 11, further comprising: collecting, by the host controller, the first and second sensed data from the plurality of sensors; andcorrelating, by the host controller, the first and second sensed data based on the event detection time. 13. The method of claim 12, wherein collecting by the host controller, the first and second data comprises: processing, by the plurality of sensors, the first and second sensed data to produce processed data; andcollecting, by the host controller, the processed data from the plurality of sensors. 14. A system comprising: a master/slave data bus;a plurality of sensors; anda master controller configured to communicate digitally with the plurality of sensors over the master/slave data bus, wherein the master controller is configured to command the plurality of sensors into an event monitoring mode over the master/slave data bus;wherein the plurality of sensors are configured to digitize and retain a first amount of data during a listening mode of the event monitoring mode and detect an event based upon the first amount of data; andwherein the plurality of sensors are further configured to drive an event trigger on the master/slave data bus upon detection of the event, wherein the event trigger is a known logic state or pattern on the master/slave data bus; andwherein the plurality of sensors are further configured to digitize and retain a second amount of data following detection of the event trigger on the master/slave data bus and record the second amount of data as event data; andwherein the plurality of sensors are further configured to return to the listening mode following recording of the event data, unless a duration associated with the event monitoring mode has expired or the master controller has commanded the plurality of sensors to exit the event monitoring mode. 15. The system of claim 14, wherein the master controller is configured to record an event time upon detection of the event trigger on the master/slave data bus. 16. The system of claim 14, wherein the plurality of sensors are configured to record an event time upon detection of the event or upon detection of the event trigger on the master/slave data bus. 17.
