What is a Data Logger?

A data acquisition device is designed to work with a computer to capture and store data. On the other hand, a data logger is a data acquisition device and computer that are in one box. They are the unsung heroes in many industries, including those where data monitoring is crucial. These compact electronic devices are designed to monitor and record data over time automatically. Imagine a tiny, tireless assistant that watches everything from temperature and humidity to pressure and vibration day or night. Data loggers play a pivotal role in various sectors by providing a reliable and efficient way to collect critical data, making them an invaluable investment for any industry. Some require additional software to set up, while others do not. The WebDAQ series from Digilent does not require additional software. All that is needed to set up a WebDAQ is an Internet Browser like Edge, Chrome, and Firefox, and it does not matter if it is Windows, Mac, or Linux.
