What Is A Data Logger?

Discover our guide on data loggers to find out whether a data logger is right for you.

What is a data logger?

The Loggershop data logger definition: A data logger is a device which measures and stores environmental data from sensors or inputs against time in its internal memory. Stored data can be extracted and analysed by a computer or mobile device. Data loggers available at Loggershop can record temperature, humidity, voltage, current mA and A, pulse, event and state, shock and vibration, carbon dioxide, pressure and light levels.

How does a data logger work?

A data logger works by measuring an environmental parameter such as temperature using an internal thermistor or external thermocouple and sensors. For example, the RTR-502 is a wireless temperature data logger with external sensor to record air, liquid and appliance temperatures. A recording interval is set that time stamps each measured reading and provides users with a means to extract and analyse what has been collected compatible with existing I.T infrastructure.

Advantages of data logging

The main advantages of using a data logger is its ability to record historic data and alert users of a change in conditions. Knowing what has happened historically is important when looking to prove conditions have been within acceptable or pre-planned limits but also to better understand the impact on a product or the built environment over time. Knowing what is happening in the moment and over time enables users to act before there is a detrimental impact on a product, personnel or infrastructure. For example, a supermarket may need to prove that their produce has consistently been kept in certain temperatures and that the temperature has not increased through the transport process, which may spoil it. Data loggers available at Loggershop offer the following features:
