Concept of Data Loggers
A data logger which is also commonly referred to as a data recorder is nothing but an electronic device which helps in the recording of data over time or in relation to the location with either an instrument or sensor that is already built in. In some of the cases, it is done with the help of external instruments and sensors as well. Nowadays, they are based on a processor of a digital nature are being increasingly used but not completely. The data loggers are usually very small and portable device powered by a battery. These are equipped with a microprocessor, sensors and internal memory for the storing of data.
There are some of the data loggers which interface with a computer and make the use of a software for its activation and viewing as well as analysing the data so collected. On the other hand, there are other data loggers which have a logical interface device that is a keypad and LCD that can be used as a stand-alone device.
Application for Cold Chain
Cold chain refers to the storage, shipping and distribution of the products which requires to be kept in a specialised environment that is controlled by temperature. A cold chain when kept unbroken, it makes sure that the quality and freshness of all the goods are kept intact. The monitoring of cold chain is an extremely common practice in the industries of food and pharmaceuticals because these products are very sensitive to fluctuating temperatures. Data loggers play a vital role in this regard which are as listed below.
- The data loggers are extremely helpful in monitoring the temperature throughout the cold chain process.
- The overall history of the temperature is kept recorded by these data loggers.
- The documenting of the temperature throughout the process of cold chain makes sure that the quality of all the products are kept intact without any compromise in it.
- These data loggers can automatically record temperatures on a 24-hour basis. Once they are activated they need not require any more attention and can be left unattended during the monitoring period but still provides with accurate results.

Thus, it can be very well understood how the data loggers are important in the field of cold chain applications and provides a very easy to use solution for the necessary temperature reporting during the overall process.
