What are data loggers

Data logging devices are electronic devices part of the Internet Of Things (IOT) category (4), which record data over time or about location (1). They’re also known as data loggers or data recorders, and here are some key points about them:

 

  • Components: They typically consist of a microprocessor, internal memory for data storage, and sensors (1)(2). Some data loggers also have a built-in instrument or sensor, while others record data via external instruments and sensors (1).
  • Operation: Data loggers can operate independently of a computer, unlike many other types of data acquisition devices (2). They are generally small, battery-powered, and portable¹². Some data loggers interface with a personal computer and use software to view and analyze the collected data, while others have a local interface device (like a keypad or LCD) and can be used as a stand-alone device (1).
  • Types: Data loggers vary from general-purpose types for a range of measurement applications to very specific devices for measuring in one environment or application type only (1). They can be single, stand-alone units or consist of multiple channels (2).
  • Input Types: Data loggers can accept different input types such as pressure, temperature, humidity, voltage, and current (2). Some data loggers can even accept all types of input (2).
  • Applications: They are used in various applications, including verifying temperature and humidity levels of storage and transportation facilities, providing building maintenance information, monitoring growing conditions in the agricultural industry, monitoring medicine storage in a medical facility, and monitoring the temperature of food (2).
  • Cost: The cost of data loggers has been declining over the years as technology improves and costs are reduced. Simple single-channel data loggers cost as little as $25, while more complicated loggers may cost hundreds or thousands of dollars (2).

Recording Duration: The recording duration depends on the memory capacity of the data logger and the desired sample rate (2).

In summary, data loggers are versatile, multi-purpose tools suitable for multiple applications (3) part of a whole field data collection or inspection process.

What do data loggers do?

Data logging devices monitor and record changes in environmental conditions over time. They can be used independently of a computer and are often small, battery-powered, and portable. Here’s a brief overview of their functions (5)(6):

  • Monitoring: Data loggers use sensors to collect data on various parameters such as temperature, humidity, pressure, voltage, and current.
  • Recording: They store the collected data in an internal memory for later retrieval and analysis.
  • Versatility: They come in different shapes and sizes, with some capable of handling multiple inputs and others designed for specific measurements.
  • Applications: They are used in numerous fields, including transportation, agriculture, medical facilities, and food storage, to ensure optimal conditions are maintained.

 

Data loggers are essential tools for ensuring product quality, optimizing processes, and conducting research and development across various industries.
