1. A transport refrigeration unit (TRU), comprising:
an enclosure;
a first sensor in the enclosure controlled by a first controller that is within the first sensor or remotely located, the first sensor being an ultra-wide band (UWB) radar sensor,
wherein the first controller monitors for cargo in the enclosure by:
scanning the enclosure periodically and/or in response to one or more trigger events, and
identifying, from scanned data, cargo presence, cargo type, cargo quantity and cargo distribution within the enclosure;
a refrigeration system/air conditioner and a refrigeration system/air conditioner controller controlling the refrigeration system/air conditioner and communicating over a network with the UWB radar sensor,
wherein upon the first controller identifying the cargo presence, the cargo type, the cargo quantity and the cargo distribution within the enclosure, the first controller:
determines refrigeration/air conditioning requirements within the enclosure for the cargo based on the identified cargo presence, cargo type, cargo quantity and cargo distribution, and
instructs the refrigeration system/air conditioner to condition air in the enclosure based on the identified cargo presence, cargo type, cargo quantity and cargo distribution.
