1. A system comprising:
a. a sensor module comprising a plurality of sensors configured to produce measurements of discrete characteristics of an environment in which the sensor module is located, and wherein the sensor module includes an audio indicator and a module processor; and
b. one or more processors configured to:
i. receive a set of sensor data produced by the plurality of sensors over a period of time, wherein the set of sensor data comprises a plurality of discrete characteristic measurements;
ii. create a fused sensor dataset that identifies one or more correspondences between the plurality of discrete characteristic measurements during the period of time; and
iii. determine whether an emergency scenario exists based upon the fused sensor dataset and, where the emergency scenario exists, provide an emergency notification, and
wherein the module processor is configured to:
i. in response to the set of sensor data being produced, perform a local analysis of the set of sensor data to determine whether the emergency scenario exists prior to or in parallel with providing the set of sensor data to the one or more processors; and
ii. where the emergency scenario exists based on the local analysis, provide a local emergency notification via the audio indicator.
