Abstract: A method and system for cold chain monitoring of perishable goods includes at least one environmental sensor (102) to monitor at least one environmental parameter, a controller (104) to log a plurality of readings from each of the at least one environmental sensors (102), and a machine readable display (114) to display at least one alarm status associated with the plurality of readings via a barcode.

Abstract: One embodiment of the invention is directed to a temperature monitor comprising a housing, a temperature sensor to provide temperature indications, wherein the temperature sensor is disposed inside the housing and exposed to an ambient temperature, circuitry within the housing for processing and storing the temperature indications, and a power supply within the housing and coupled to the circuitry. The power supply is adapted to provide a level of power to the circuitry sufficient for the operability of the circuitry at least at any ambient temperature between ?40° C. and ?80° C. Another embodiment of the invention is directed to a method comprising acts of exposing the interior of a housing to a temperature below ?40° C., measuring the temperature in the interior of the housing, storing an indication of the temperature within the housing, and processing the indication of the temperature within the housing.
