Data acquisition systems can be classified based on their functionality and the method of data collection:
PC-based DAQ: Utilizes the processing power, display, and connectivity of personal computers with DAQ hardware for data collection and analysis.
Standalone or portable DAQ: Independent systems that can operate without a PC, often used for field measurements or when portability is required.
Networked DAQ: Systems connected over a network, allowing for remote monitoring and control across multiple locations.
Modular DAQ: Systems that can be customized with different modules for various types of inputs and outputs to meet specific application requirements.
