What is a data logger?

Data loggers are electronic devices that record data over time with either a built-in sensor or external sensors. They are usually small and portable and are powered by batteries. They have microprocessor, internal memory for data storage and sensors. Some data loggers interact with a computer and require software to be activated and view and analyze the collected data, while others have a local interface device (LCD screen and buttons) and can be used as a standalone device. However, the vast majority of manufacturers classify the datalogger as a stand-alone device capable of reading electrical signals linked to the measurement of magnitudes, such as temperature, humidity, voltage ... etc. The data is stored in an internal memory and is accessible from specialized software or in some cases in the form of a PDF report when the device is connected to the computer.

What advantages do they have?

The main advantage of these data acquisition systems is that the information is not lost when we are not observing the instrument but it is stored which allows it to be analyzed a posteriori from any PC.

What types of data logger are there?

Given its function of data collection, the applications of these instruments have virtually no limit in the industry. In the same way for the same application there is a wide range of models ranging from simple design devices and affordable prices to instruments specifically designed for very specific applications that can cost hundreds or even thousands of euros. The dataloggers available on our website measure magnitudes such as the temperature and humidity data logger and even the voltage or amperage.

How to choose a datalogger?

The choice of a datalogger is determined by the application to which the instrument will be destined as well as the working conditions to which it will be subjected. For example, if you want to place a datalogger in the trailer of a freight truck to control the temperature at which a shipment of fruit will travel you will need a type of datalogger if you want to measure the temperature at 5m depth of a fish farm you will need another. We must take into account the datalogger's specifications to know if it fits our needs.
