Learn IOTC with Real Code Examples

IoTC enables everyday objects to connect to the internet, allowing data collection, remote control, and real-time analytics.

It combines hardware (sensors, actuators), software (middleware, cloud services), and communication protocols (MQTT, CoAP, HTTP).

Applications range from smart homes and industrial automation to healthcare, agriculture, and smart cities.

Embedded hardware with sensors and actuators

Communication via Wi-Fi, Bluetooth, Zigbee, LoRaWAN, or cellular networks

Data analytics using cloud or edge computing

Event-driven architecture and automation rules
