Sensor technologies refer to devices that detect and respond to physical stimuli, such as light, temperature, motion, or pressure. These sensors convert the detected information into signals that can be measured and analyzed. Common examples include temperature sensors used in thermostats and motion sensors found in security systems. These technologies play a crucial role in various applications, including automotive systems, smart homes, and industrial automation. By providing real-time data, sensor technologies enhance efficiency, safety, and convenience in everyday life and various industries.
