A sensor is an electronic or mechanical device used to detect changes in the environment, such as temperature, pressure, light, humidity, motion, or gases. It converts physical changes into electrical signals that can be analyzed by control or processing systems.
In today’s world, sensors are the foundation of many modern technologies. From smartphones and smart vehicles to industrial production lines and medical equipment, they all rely on the precise performance of sensors.
Sensors are available in many different types, including temperature sensors, pressure sensors, photoelectric sensors, humidity sensors, and motion sensors. The choice of sensor depends on the application, required accuracy, and environmental conditions.
In industry and research, the use of accurate sensors improves safety and quality while reducing costs. Therefore, understanding how sensors work and where they are used is essential.
