What is an IoT app?

IoT stands for the ‘Internet of Things’. Sounds a bit techy, but think about it as giving everyday objects the ability to connect to the internet and communicate with each other.

Let's take a smartwatch for example. This device tells you more than just the time. It tracks your steps, monitors your heart rate, and even connects to your phone to show notifications. Now, take that idea and apply it to all sorts of things. Your refrigerator can tell you when you're out of milk, your thermostat can adjust the heat according to the weather, and your car can guide you to the fastest route home. All these devices connect to the internet and share data, creating the ‘Internet of Things’.

IoT apps are software programs that help smart devices connect to the internet and interact with each other. These apps make it possible for devices to gather data, make decisions, and perform tasks automatically.

How do IoT apps work?

1. Connection to devices: IoT apps connect to devices using the internet — typically, apps use protocols like Bluetooth, Wi-Fi, and other ones like Z-Wave or Zigbee. This connection allows the app to send or receive data.
2. Data collection: Smart devices come equipped with sensors, such as temperature, motion, light, or humidity sensors. These sensors continuously gather data from their environment and prepare it for transmission. Then the app gathers information from the sensors. For example, a smart fridge app collects data about what's inside your fridge.
3. Data processing: Once the app collects the data, it processes the information to help you understand it better. It might display this data in simple charts or send alerts.



4. Commands and control: IoT mobile apps can also send commands back to devices. You might use an app to turn on your smart lights or to adjust the temperature in your home. There are also multiple voice control devices like Amazon Alexa that can be used to command the devices.
