A data acquisition and control (DAC) system, often coupled with an interactive online laboratory (IOLab), provides a platform for real-time data collection, analysis, and experimental control. This integrated system enables users to conduct experiments remotely, acquire data from various sensors, and manipulate experimental parameters in a controlled environment. A typical example involves measuring acceleration, force, and magnetic field strength using a handheld device interfaced with a computer running specialized software.
Such systems offer significant advantages in educational and research settings by removing geographical barriers to laboratory access and enabling cost-effective experimentation. Historically, these tools developed from bench-top laboratory equipment to sophisticated computer-interfaced systems, driven by advances in microelectronics and software development. The ability to perform repeatable, controlled experiments and to analyze data immediately contributes to a deeper understanding of physical principles.
