Sensors & Transducers
Sensors and transducers are essential electronic devices and components that detect physical quantities such as temperature, pressure, light, or motion and convert them into electrical signals. Sensors typically sense changes in the environment, while transducers transform one form of energy into another. These components are crucial in automation, measurement, and control systems, enabling accurate data acquisition and real-time monitoring in various applications, from industrial machinery to consumer electronics.
