A data logger is an electronic or battery-powered instrument that records environmental conditions such as temperature, relative humidity, and light levels over periods of time. Data loggers are connected to a computer terminal and proprietary software is used to download the recorded data and produce needed reports. One of the primary benefits of using data loggers is the ability to automatically collect data on a 24-hour basis. Upon activation, data loggers are typically deployed and left unattended to measure and record information for the duration of the monitoring period. This allows for a comprehensive and accurate picture of the environmental conditions being monitored, such as air temperature, and relative humidity. Data loggers typically have slower sample rates.

Data loggers are implicitly stand-alone devices, whereas a typical data acquisition system must remain tethered to a computer to acquire data. This stand-alone aspect of data loggers implies on-board memory that is used to store acquired data.
Sometimes this memory is very large so it can accommodate many days, or even months, of unattended recording. This memory may be either a battery-backed static random access memory, flash memory, or EEPROM. Given the extended recording times of data loggers, they typically feature a time- and date-stamping mechanism to ensure that each recorded data value is associated with the date and time of acquisition.
