Intelligent Sensors are advanced sensing devices that combine traditional sensor technology with embedded processing capabilities, enabling them to collect, analyze, and respond to data in real time. Unlike conventional sensors that merely detect changes in physical conditions such as temperature, pressure, or motion, intelligent sensors can process information on the spot, communicate with other systems, and even make autonomous decisions. These sensors are integral to modern applications across industries such as healthcare, automotive, industrial automation, smart homes, and IoT (Internet of Things). Their ability to enhance accuracy, efficiency, and automation makes them a cornerstone in the development of smart technologies and next-generation systems.
