“Sensor technology” enables smart devices to collect, measure, and analyze environmental data, facilitating greater interactivity and automation. These sensors can detect various stimuli, such as temperature, motion, light, and humidity, and convert them into digital signals for processing. By integrating these sensors, smart devices can adapt to user behaviors, enhance energy efficiency, and improve overall functionality. This technology is vital in applications such as smart homes, healthcare monitoring, and industrial automation, driving innovation and convenience in everyday life.
