The Many Uses of Data Loggers

Data loggers are electronic devices designed to accurately collect and store specific or universal values, often without the use of a PC. This provides a way for you to log data at any location, at any time, and then to return at another date and time to download the readings to your computer. This is often done with a USB stick or cable, and the benefits of this are many and varied, especially if you have complex needs in and out of the field.


A data logger in Singapore is commonly used in a wide variety of industries and for many different applications. For example, you could use it for agriculture and horticulture, monitoring temperatures in the transportation and storage of food, monitoring both internal and external environments, and much more. This will allow you to accurately collect and store data in real time, so as to keep up with changes or anomalies as they occur, which can help reduce reaction times and prevent serious problems from causing delays or interruptions of your work.


Most data loggers are battery-operated, but some models may be externally powered. These typically require very little power to operate and can thus be used for a number of years before the batteries must be replaced or recharged. You should note the battery life of your chosen data logger, as it will vary considerably based on the manufacturer, model, and how often readings are taken.

Many data loggers also have non-volatile memory to ensure that the recorded data is safe even if the battery should fail or power should be disconnected. The logger’s software will tell you when the battery is running low, which should help you avoid any interruptions in the logging system. You can also choose a model with a battery that can be replaced by hand if you prefer to do that.


Depending on the model, most loggers are more than accurate enough to cover most applications. If you plan to monitor a product at room temperature, a logger accurate within a few degrees should be good enough. This should help to keep the cost low, but some applications may benefit from a high-accuracy, slightly more costly option that can offer accuracy within one-tenth of a degree.

Number Needed

The number of data loggers you will need is entirely dependent on the number of areas which must be covered and the number of monitoring points needed to complete your project. For example, it could be that you have just one room to cover but multiple points within that room, requiring that you use multiple loggers even in that small space. Data loggers may be configured with anywhere from one to hundreds of inputs, which may help you to significantly reduce the amount of loggers actually needed for your project.

Length of Recording

Many data loggers will reliably collect data for at least a few years, although cold-chain data loggers are available which can do the job in just one trip and at a low cost. Modern loggers can take a sample each second, which is more than enough for most cold-chain applications.
