	'''Temperature Data Logger''', also called temperature monitor, is a portable measurement instrument that is capable of autonomously recording temperature over a defined period of time. The digital data can be retrieved, viewed and evaluated after it has been recorded.[[Data Loggers]]		'''Temperature Data Logger''', also called temperature monitor, is a portable measurement instrument that is capable of autonomously recording temperature over a defined period of time.

	A variety of constructions are available. Most have an internal thermistor or thermocouple or can be connected to external sources. Sampling and measurement are periodically taken and digitally stored. Some have a built in display of data or out-of-tolerance warnings. Data retrieval can be by cable, RFID, wireless systems, etc. They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with personal computers or smart phones for set-up, control, and analysis.Some include other sensors such as relative humidity, wind, light, etc. Others may record input from GPS devices.

	Modern digital data loggers are very portable and record the actual times and temperatures. This information can be used to model product degradation and to pinpoint the location and cause of excessive exposure.The measured data reveals whether the goods in transit have been subjected to potentially damaging temperature extremes or an excessive Mean kinetic temperature. Based on this data, the options may be:		Modern digital data loggers are very portable and record the actual times and temperatures. This information can be used to model product degradation and to pinpoint the location and cause of excessive exposure.The measured data reveals whether the goods in transit have been subjected to potentially damaging temperature extremes or an excessive Mean kinetic temperature. Based on this data, the options may be:


	* If there have not been out of tolerance temperatures for critical times, continue to use the shipment, without special inspection		* If there have not been out of tolerance temperatures for critical times, continue to use the shipment, without special inspection


	* If potentially damaging temperature hazards have occurred, thoroughly inspect the shipment for damage or degradation. Possibly accelerate sale and use because of reduced shelf life.		* If potentially damaging temperature hazards have occurred, thoroughly inspect the shipment for damage or degradation.

	* The time of the temperature extreme, or GPS tracking, may be able to determine the location of the infraction to direct appropriate corrective action.		* The time of the temperature extreme, or GPS tracking, may be able to determine the location of the infraction to direct appropriate corrective action.
