Sensors

Definition

Sensors are devices that detect and respond to physical stimuli, translating these inputs into signals that can be understood by a system. They play a critical role in providing feedback about the environment, enabling systems to perceive changes and adapt accordingly. The integration of sensors is vital for the development of responsive technologies, enhancing functionality across various applications.

5 Must Know Facts For Your Next Test
