1. A mobile environmental sensor system, comprising:
a first mobile environmental sensor disposed on a transport unit;
a controller, disposed on the transport unit, configured to electronically communicate with the first mobile environmental sensor; and
a network transmitter, disposed on the transport unit, configured to electronically communicate with the controller, wherein the controller comprises:
a processor, and
a memory,
the processor configured to:
trigger a measurement from the first mobile environmental sensor;
receive a sensed value from the first mobile environmental sensor;
compare the sensed value as received from the first mobile environmental sensor to a reference sensed value received by the controller from a stationary reference environmental sensor via the network transmitter;
calibrate the first mobile environmental sensor based on the comparison of the sensed value and the received reference sensed value when detecting that the stationary reference environmental sensor has electronically communicated with the first mobile environmental sensor of the transport unit within a selected amount of time or when detecting that the transport unit is within a selected distance from the reference environmental sensor;
activate one or more components of the climate control system based on the sensed value;
detect that the transport unit is passing within a selected distance of another transport unit;
detect that the stationary reference environmental sensor of another transport unit has electronically communicated with the first mobile environmental sensor of the transport within a selected amount of time; and
calibrate the first mobile environmental sensor of the transport unit using the stationary reference environmental sensor corresponding to the another transport unit.
