Smart Sensors: Enabling Intelligent and Connected Systems
Smart sensors are advanced sensing devices that combine traditional sensors with embedded microprocessors, communication interfaces, and software to gather, analyze, and transmit data in real time. Unlike basic sensors that only detect physical changes, smart sensors can process data locally, communicate with other devices, and support automation and decision-making in a wide range of applications.
These sensors are critical components in the Internet of Things (IoT) ecosystem, playing a key role in smart homes, industrial automation, healthcare, transportation, and more.
