A sensor is a device that detects and responds to changes in its environment, converting physical input—such as light, heat, motion, pressure, or chemical composition—into signals that can be measured or recorded. Sensors are essential components in a wide range of technologies, from medical diagnostics and environmental monitoring to robotics and smartphones. They enable systems to perceive and react to the world, often serving as the front line in data collection for scientific research and engineering applications. Ongoing innovations in sensor design and miniaturization are expanding their capabilities and use in increasingly complex and sensitive applications.
