Ohio Pen/10200220

CLEVELAND - OhioPen -- Do you need a way to collect data, but don't know where to start? We put together this comprehensive guide just for you.

What is a Data Logger?

A data logger, or datalogger, is an electronic device designed to measure and store data values, often independently of a PC. Nowadays most data loggers are compact and relatively inexpensive. Dataloggers may be single-input devices or may accept inputs from multiple types of sensors.

Advantages of a Data Logging:

Being more reliable and accurate than manual measurements, data loggers save personnel the time otherwise spent taking down reading and recording measurements on paper. Whether you have a short- or long-term problem to solve, data loggers give you an automated solution for both monitoring and recording information.

Why Use Data Logging?

A typical application for a data logger is to record and monitor the temperature of a specific product or environment, like a vaccine storage refrigerator.  The data logger will operate 24/7 including the weekends, holidays, or outside of work hours when no person is available for the task.  Data loggers are also used for more complex tasks such as recording multiple sensor data from machines for diagnostic purposes or to identify areas for energy savings.

What Do You Need to Measure?

Now ask yourself, "What type of data do I need to measure?"

Most commonly, the answer is temperature, but what if you need to also log humidity, or what if you need to log both temperature and carbon dioxide levels? Fortunately, there are a wide variety of devices on the market with internal or external sensors to measure the data you need.

Easy Data Retrieval:

Typically, data loggers save their measurements to a memory card or other internal memory for convenient retrieval. More advanced models can also transfer the data automatically over your choice of communications. These include but are not limited to:
  • Ethernet
  • WiFi
  • Cellular Modem
  • Proprietary Wireless
  • Bluetooth

How Do I Set Alarms?

Today's technology gives you several choices of how you'd prefer to receive alarms. For example, alarm notifications can consist of anything from bright LED indicators and loud audible alerts to data loggers with external alarm outputs for connection to sirens, lights, etc.
