Data Logging

LabJack produces a variety of DAQ devices that can be used as data logging devices when paired with a computer and using one of the available logging applications. Temperature can be logged by pairing one of many different temperature sensors. A large variety of other sensors and measurement instruments can also be used that allow for detection and measurement of humidity, light, accelerometers, gyroscopes, and more. For example, when pairing an EI-1050 with either a T4 or a T7 both Temperature and Humidity data can be collected, graphed, and logged to a .csv file using the LJLogM application.

The logging capabilities of our T-Series devices (T7 Series and T4 Series) can be greatly enhanced with the use of Lua Scripts to collect, format, and report data from a wide range of I2C sensors that can then be collected using LJLogM.

Using the LJM driver and our published example code custom logging applications can be created, allowing our devices to be used with the Raspberry Pi and other single board computers.

LabJack's devices can be connected to a computer over three communication mediums: USB, Ethernet, and WiFi. In short, we design, manufacture, and produce USB, Ethernet, and WiFi DAQ devices that fulfil a wide array of data acquisition and control needs ranging from data logging to intelligent feedback driven control systems.

LabJack Software Options

The LJM Library is a set of functions used to easily communicate with several of our devices using a simple Modbus over USB interface (as well as Modbus TCP/UDP when applicable). The goal is to be easy to use and understand, yet flexible.
All important values and data from the device can be read and/or written by using the associated register(s).
