A data logger, or data recorder, is a battery-powered, compact device with an internal processor, data storage and one or several sensors. These devices can be used in many different environments and record measurements at predetermined intervals. These devices monitor and record environmental variables over time. This allows conditions to be assessed, documented, analysed, and validated. The data logger is equipped with a sensor that receives the information, and a chip computer to store it. The data is then transferred from the data logger to a computer and analyzed. Learn more about data loggers in our guide .
In all sorts of applications, including research, performance monitoring, and analysis, data loggers are used. They are therefore used in a wide range of industries. They are designed to store and capture large volumes of accurate measurement data. This is usually done to track environmental parameters over a certain time period, process or location.
Sensors or other detection instruments calibrated to detect certain environmental stimuli are used to gather the information. Sensors can be integrated into a device or mounted externally.
The majority of today’s loggers are battery powered, compact, and highly portable. They form an important part of the data collection area. These loggers can be used almost anywhere and are a modern upgrade to older data collection equipment like chart recorders.
Depending on which data logger you use, measurements can include air temperatures, humidity, AC/DC voltage and current, differential pressure and time of use (lights and motors). Light intensity, water temperatures, water levels, dissolved oxygen and soil moisture, rain, wind speed, direction and leaf wetness.
