Smart sensors are advanced sensing devices designed to collect data from their surroundings and process it locally before sending it to other systems. Unlike traditional sensors that only detect physical changes such as temperature or pressure, smart sensors combine sensing elements with embedded processors, communication modules, and software logic.
Smart sensors are designed to collect and process data in environments where real-time monitoring and automated responses are required. They convert physical conditions such as temperature, pressure, or motion into digital signals that systems can analyze and act upon.
These devices are essential components of modern connected technologies, supporting automation and data-driven decision-making across industries.
