IoT Trainer Kit – Advanced Learning and Development Platform

The Internet of Things (IoT) represents the seamless interconnection of physical devices—sensors, actuators, controllers, and machines—through the Internet or dedicated networks. IoT enables real-time data acquisition, remote monitoring, and intelligent decision-making across domains such as smart homes, healthcare, transportation, agriculture, and industry. An IoT ecosystem generally involves three major layers:

• Perception Layer – sensors and devices for data acquisition

• Network Layer – communication technologies for data transmission
