Data acquisition, or DAQ, is the process of measuring and collecting data from various sources, typically involving the use of sensors to convert physical parameters such as temperature, pressure, strain, and force into electrical signals. These signals are then filtered, conditioned, and digitized using high-precision measurement amplifiers and A/D converters. The digitized data is transferred to a data logger unit via buses such as CAN, EtherCAT, Ethernet, or proprietary buses, which synchronously stores the data. In addition to sensor-based data acquisition, modern DAQ systems can also collect digital data from various sources, such as engine control units and machine controllers, using digital interfaces. The goal of data acquisition is to obtain accurate and reliable data that can be used for analysis, monitoring, and control purposes.
