Data Acquisition & Signal Conditioning
This module explores how mechatronic systems sense the physical world. Data Acquisition (DAQ) is the process of converting real-world phenomena like temperature or pressure into digital data a microcontroller can understand. Signal Conditioning is the vital step of cleaning and preparing raw sensor signals for accurate digital conversion. Instead of just reading, use the interactive labs in this module to build a hands-on intuition for these critical concepts.
Navigate using the tabs above to explore the interactive labs, see real-world applications, and test your knowledge.
