OpenLogger: High Resolution Portable Data Logger
OpenLogger is a high-resolution data logger designed to provide quality measurements without the limits of traditional data logging or data acquisition solutions.
Engineers, scientists, and data enthusiasts can take advantage of eight analog channels, two power supplies, a function generator, eight digital I/O, and a wireless connection to deploy a data logging system compatible with a wide range of sensors.
Data can be streamed to the user interface, WaveForms Live, or logged to an SD card providing the ability to save large amounts of data and check the status of systems in real-time. WaveForms Live is open-source and browser-based and can be accessed at WaveFormsLive.com.
We believe that engineers shouldn't be limited by the tools available to them, so we equipped OpenLogger with features that enable operation in a wide range of conditions. OpenLogger can be powered via a USB battery pack or barrel jack power supply, so it can be connected and powered by a computer or externally and set up for long-term testing. OpenLogger can connect to WaveForms Live over WiFi or USB, which allows it to be used when electrical isolation or freedom from a wired connection is necessary.
The OpenLogger comes with a protective acrylic case, flywires for connection via female-terminated wires, and a sheet of labels for the flywires. We also offer an option to bundle the OpenLogger with an Accessory Kit, which includes a clear project box, a micro USB cable, and 8G microSD card, and the Screw Terminal Adapter.
