What Are Sensors?
A sensor is a device that detects and responds to physical or environmental stimuli such as temperature, light, pressure, motion, and chemical composition. Sensors convert these stimuli into electrical signals, which can then be read or analyzed by machines, systems, or human operators. In recent years, sensors have become integral to the functionality of smart devices, IoT applications, industrial systems, and health monitoring technologies.
Sensors are categorized into different types, such as temperature sensors, pressure sensors, optical sensors, motion sensors, gas sensors, and more, based on the specific stimuli they detect. These devices are critical for enabling automation, enhancing efficiency, and improving safety and quality across various sectors.
