Compact freight sensor packages and methods of monitoring transport processes using same

A device, comprising:

• a mmWave radar sensor;
• at least one of an imaging sensor or an audio input device;
• and
• a processor in communication the mmWave radar sensor and a memory, the processor configured to at least:
• receive a cargo signature associated with an interior of a container, the cargo signature comprising a combination of sensor data from the mmWave radar sensor and at least one additional sensor;
• receive, from the mmWave radar sensor, data related to a change associated with an object or an environment within the interior of the container;
• instruct a comparison between the data related to the change and the cargo signature;
• determine an event based on the comparison;
• responsive to determination of the event, instruct actuation of at least one of the imaging sensor or the audio input device to capture imaging or audio data associated with the event;
• and
• store the event within the memory.
