[[File:Data logger application for weather station.jpg|thumb|Data logger application for weather station at P2I [[Indonesian Institute of Sciences|LIPI]] ]]
Applications of data logging include:
* Unattended [[weather station]] recording (such as [[wind speed]] / direction, [[temperature]], [[relative humidity]], [[solar radiation]]).
* Unattended hydrographic recording (such as water level, water depth, water flow, water pH, water conductivity).
* Unattended soil moisture level recording.
* Unattended gas pressure recording.
* Offshore buoys for recording a variety of environmental conditions.
* Road traffic counting.
* Measure [[temperature]]s (humidity, etc.) of perishables during shipments: [[Cold chain]].<ref>{{Cite journal

=== Examples ===
* [[Black box|Black-box (stimulus/response)]] loggers: 
** A [[flight data recorder]] (FDR) is a piece of recording equipment used to collect specific aircraft performance data.  The term may also be used, albeit less accurately, to describe the [[cockpit voice recorder]] (CVR), another type of data recording device found on board aircraft.
** An [[event data recorder]] (EDR) is a device installed by the manufacturer in some [[automobile]]s which collects and stores various data during the time-frame immediately before and after a crash.
** A [[Voyage Data Recorder|voyage data recorder]] (VDR) is a data recording system designed to collect data from various sensors on board a ship.
** A [[train event recorder]] is a device that records data about the operation of train controls and performance in response to those controls and other train control systems.
** An [[accident data recorder]] (ADR) is a device for triggering accidents or incidents in most kind of land vehicles and recording the relevant data. In automobiles, all [[Diagnostic Trouble Code|diagnostic trouble codes]] (DTCs) are logged in [[engine control unit]]s (ECUs) so that at the time of service of a vehicle, a service engineer will read all the DTCs using [[Tech-2]] or similar tools connected to the [[on-board diagnostics]] port, and will come to know problems occurred in the vehicle. Sometimes a small [[on-board diagnostics#Data loggers|OBD data logger]] is plugged into the same port to continuously record vehicle data.
** In [[embedded system]] and digital electronics design, specialized high-speed digital data logger help overcome the limitations of more traditional instruments such as the [[oscilloscope]] and the [[logic analyzer]]. The main advantage of a data logger is its ability to record very long traces, which proves very useful when trying to correct functional bugs that happen once in while.
** In the racing industry, Data Loggers are used to record data such as braking points, lap/sector timing, and track maps, as well as any on-board vehicle sensors.
* [[Health|Health data]] loggers:
** The growing, preparation, storage and transportation of food. Data logger is generally used for data storage and these are small in size.
** A [[Holter monitor]] is a portable device for continuously monitoring various electrical activity of the cardiovascular system for at least 24 hours.
** [[Electronic health record]] loggers.
* Other general [[data acquisition]] loggers:
** An (scientific) experimental testing data acquisition tool.
** Ultra Wideband Data Recorder, high-speed data recording up to 2 Giga Samples per second.
