Sensor technology refers 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. The applications of sensor technology are vast, spanning various fields like healthcare, automotive, and environmental monitoring. For instance, medical sensors can monitor vital signs, while automotive sensors enhance vehicle safety by detecting obstacles. Overall, sensor technology plays a crucial role in improving efficiency and safety in everyday life.
