What is Data Acquisition – DAQ?

Data acquisition, or DAQ as it is commonly known, is the act of digitizing data from the surrounding environment so that it may be presented, processed, and saved on a computer. The measurement of a room's temperature as a digital value using a sensor such as a thermocouple is a straightforward example. Modern data collecting systems may incorporate data analysis and reporting software, network connectivity, and remote control and monitoring capabilities.

Digilent DAQ Hats are RaspberryPi-compatible and are very popular among industrial customers. Models are available with voltage, thermocouple, IEPE-based sensor inputs and analog outputs. Digital I/O enables end-users to construct multifunctional Raspberry Pi-based data logger systems. All DAQ HATs feature open-source libraries including C/C++® and PythonTM examples. In addition, exhaustive API and hardware documentation are supplied.
