What is a Data Logger?

A data logger is a compact, battery-powered device equipped with an internal microprocessor, data storage, and one or more sensors or sensor ports. Data loggers can be deployed and left unattended in a variety of environments to record measurements at set intervals for up to years at a time.

What are the different types of data loggers?

USB data loggers are compact, reusable, and portable, and offer low cost and easy setup and deployment. Internal-sensor models are used for monitoring at the logger location, while external-sensor models enable precise sensor placement and more measurements. USB loggers communicate with a computer via a USB interface, but for greater convenience, a data shuttle device can be used to offload data from the logger for transport back to a computer. Optional waterproof data shuttles are available for optical USB loggers used in submersible water monitoring applications.
Bluetooth-enabled data loggers are also compact, reusable, portable, easy to set up and deploy, and offer the added benefit of wireless data transmission to mobile devices or laptops within a 100-foot range. Particularly useful for monitoring hard-to-reach or limited-access areas, users can download data, view data in graphs, check the logger’s operational status, share data files, and store data in the cloud.
Web-based data logging systems provide remote, around-the-clock, internet-based access to data via cellular, Wi-Fi, or Ethernet communications to the system. These systems, which can be configured with a variety of external plug-in sensors and/or wireless sensors, transmit collected data to a secure web server where users can view or retrieve data. Users can also reconfigure system settings remotely and get automatic text/email alarm notifications when conditions reach critical levels.

Where are data loggers used?

Data loggers are used in a broad range of environments, including indoors, outdoors, in water, and in transit – essentially anywhere data is needed, and the convenience of battery power is preferred.
