Data Logger Products for PC-connected, Stand-alone and Cloud-based applications

Data loggers from DATAQ Instruments address a wide range of applications, both for general- and special-purpose situations. Special-purpose data loggers are available for temperature and humidity, voltage, thermocouple, and event applications to name just a few. These are usually single-channel devices that feature low cost. Other multi-channel product solutions can measure a variety of measurements at the same time, like voltage, ac rms, 4-20 mA process current, and many more. Our full range of data logger solutions means a product to fit any application or budget. View all our Data Loggers.

Data Logger Characteristics

PC-connected Data Logger

Dependent upon a PC to acquire data, PC-connected instruments usually share these common traits:

  • Faster sampling speeds
  • Provided with software that delivers PC-based storage and a real time display of acquire data
  • Sometimes powered directly from the PC, or supplied with an external power supply

Stand-alone and Cloud-based Data Loggers

Beyond their ability to operate independently, stand-alone data logger products usually share a number of common traits:

  • Built-in memory of various sizes or the ability to support removable memory devices like SD memory cards and USB thumb drives
  • Often, but not always slower sampling rates than PC-connected data loggers
  • Often are battery-operated, or can be purchased with a battery option
  • Cloud-based solutions require Internet access

Data Logger Interfaces
Data Logger Interfaces

PC-connected Data Logger

Data loggers that need a PC to acquire data must connect to them in some manner. This is done through standard interfaces, which are found on all PCs. The most common are:

  • USB
  • Ethernet
  • WiFi (802.11-compliant)

Stand-alone and Cloud-based Data Loggers

Even though they operate without a connected PC, stand-alone data loggers need to be programmed to define how data is logged. Common ways to connect are the same as PC-connected products:

  • USB
  • Ethernet
  • WiFi (802.11-compliant)
  • Since they require Internet access Cloud-based solutions must connect via hard-wired Ethernet or WiFi

Data Logger Memory
Data Logger Memory

PC-connected Data Logger Memory

By definition, pc-connected data loggers use a PC’s memory for data storage. Software supplied or purchased with the data logger determines how the PC’s memory is used for data storage:

  • Stored to PC's RAM
  • Streamed to a PC's hard disc drive
  • Virtually unlimited storage

Stand-alone and Cloud-based Data Loggers

Memory options for stand-alone data loggers come in many shapes and sizes, but the most common forms are:

  • Built-in memory
  • USB thumb drive
  • SD memory

Data Logger Displays

PC-connected Data Logger Displays

PC-connected data loggers use a PC’s display, which offers several benefits:

  • Faster display updates
  • Fast graphical plotting of acquired data
  • More display flexibility (scroll, sweep, etc.)
  • Larger form factor for easier viewing

Stand-alone and Cloud-based Data Loggers

Some stand-alone data loggers provide built-in displays, but are generally somewhat limited:

  • Typically limited to slow update rates
  • Most offer only numeric displays
  • A few offer built-in graphical displays
  • Display form factor is always small
  • Larger form factor for easier viewing
