Introduction to Sensors
Sensors are devices that detect and respond to some type of input from the physical environment. The input can be light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena. The output is generally a signal that is converted to a human-readable display at the sensor location or transmitted electronically over a network for reading or further processing.
Sensors play a crucial role in various industries, including automotive, healthcare, consumer electronics, industrial automation, and environmental monitoring. They enable machines and systems to interact with the real world, providing data that can be used for control, monitoring, and decision - making.
