What Is IoT Development?

IoT development refers to the process of designing, building, and deploying applications, devices, and systems that are part of the Internet of Things ecosystem. IoT devices collect, analyze, and transmit data over the internet to enable automation, decision-making, and remote control.

IoT development involves multiple layers:

• Device Layer: Sensors, actuators, and microcontrollers that collect data.
• Network Layer: Connectivity through Wi-Fi, Bluetooth, LoRaWAN, Zigbee, or cellular networks.
• Edge Computing Layer: Local processing on devices or gateways.
• Cloud Layer: Data storage, analysis, and visualization.
• Application Layer: Interfaces for monitoring and controlling devices.

IoT development is not just about hardware; it also involves software, communication protocols, cloud integration, and analytics.
