Data logger

A data logger is a recording device for creating a time-sequence history of events. Data loggers are employed in many industries to ascertain environmental parameters such as temperature, pressure, humidity, and the like over a period of time. For example, data loggers are used in shipping and storage containers to measure and record environmental conditions such as temperature, humidity, pressure, and vibration. Probably the most common use of data loggers is temperature recording, with the aid of thermistors, thermocouples, or other temperature measuring devices. There are two variations on the basic data logger design. One variation is the event logger which is designed to record data during a relatively short event, such as an earthquake, while conserving available memory and power during the periods between events. The other variation is the pulse recorder which counts pulses over a given period of time. Data is then provided in the form of pulses per period. Pulse recorders are useful in connection with devices such as Geiger counters. In many cases, data loggers include memory chips or strip charts for electronic recording. Typically, data loggers include probes or sensors which measure product environmental parameters and connect to the data logger. Data loggers are capable of downloading such data through a mechanical multi-pin connector, an infrared or RF transmitter, normally found in a computer system to permit processing of such data through a data base.
