IoT is a reliable network of connected physical objects like cars, appliances, and household items. These objects use software, sensors, and connecting devices to collect and share data over the network. While many associate IoT with smart devices that simplify daily life, it also includes the Internet of Medical Things and industrial IoT, which automate industries like construction, manufacturing, and oil and gas.

The central hub to control all these connected devices and sensors in the business environment is MOBILE APPLICATION. Let’s break down the layers of an IoT app, learn how to develop one from scratch, and explore its potential costs.

Layers of an IoT Mobile App

There are 4 layers of an IoT-based mobile application. Have a look.

• IoT-connected Devices and Sensors:

The first layer of an IoT app is the connected sensors, devices, and actuators. These devices can collect data like temperature, motion, and geolocation. This data is transferred to the app’s interface. Known as the perception layer, it collects and transmits data for additional analysis or remote control.

• IoT Networks:

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.
