IoT sensor data is sent to the main application through networks. Common options include Wi-Fi, Bluetooth, 5G, Ethernet, RFID, and LPWAN. The network type depends on the device’s range: Bluetooth or Wi-Fi work for close-range devices like smartwatches, while cellular or LPWAN is better for long-range devices like tracking sensors.

• IoT Middleware:

Next is IoT Middleware in which sensor data is processed. APIs organize and format the data into a user-friendly form. The data is first collected in a data lake, then structured and stored in a data warehouse, with cloud storage playing a crucial role. IoT apps show real-time and historical data, often using machine learning algorithm for better analysis.

• IoT Application:

Users can view IoT data and control devices through the app. The interface shows data in simple formats, like graphs, and allows users to send commands, such as turning lights on/off or adjusting the temperature.

IoT layers are crucial in app development as they structure the flow of data and functionality. All these layers ensure seamless data collection, communication, analysis, and user control, providing a well-rounded and efficient IoT app experience.
