One or more of the measured cargo temperatures are compared to a preselected threshold. Operation of refrigeration a unit disposed at the cargo container in operable communication with the plurality of temperat­ ure sensors changed is based on a result of the comparison. A transportation cargo container refrigeration system includes a plurality of cargo temperature sensors configured to determine temperature a of at least portions of a cargo. A refrigeration unit and controller are connected to the refrigeration unit and the cargo temperature sensors to control operation of the refrigeration unit based on data received from the cargo temperature sensors.
