The Role of Sensors in Modern Electronics
Introduction
Sensors are fundamental components of modern electronics, enabling devices to interact with their environment by detecting physical, Chemical, and biological changes. From smartphones and wearable devices to industrial automation and healthcare systems, sensors play a crucial role in enhancing functionality, efficiency, and automation.
What Are Sensors?
A sensor is a device that detects and responds to a specific type of input from the physical world, such as light, temperature, motion, pressure, or sound. It then converts this input into electrical signals that can be processed by electronic systems.
