Master My Projects is a leading and most Trusted IOT development company in AUS, we provide IoT platforms: Mosquito MQTT, IBM blue mix IOT, AWS IOT Devices building tools: Free RTOS, Linux, Android.

A complete IoT system integrates four distinct components: sensors/devices, connectivity, data processing, and a user interface. Below I will briefly explain each component and what it does.

Sensors/Devices

As Master My Projects is leading IOT Development Company in Sydney, we work with many sensors or devices that collect the data from the environment. This could be as simple as a temperature reading or as complex as a full video feed.

We use “sensors/devices,” because multiple sensors can be bundled together or sensors can be part of a device that does more than just sense things. For example, your phone is a device that has multiple sensors (switches, camera, accelerometer, GPS, etc.), but your phone is not just a sensor.

However, whether it’s a standalone sensor or a full device, in this first step data is being collected from the environment by something.

Connectivity

The data is sent to the cloud (what’s the cloud?), but it needs a way to get there! The sensors/devices can be connected to the cloud through a variety of methods including cellular, satellite, WiFi, Bluetooth, low-power wide-area networks (LPWAN), or connecting directly to the internet via ethernet.

Each option has tradeoffs between power consumption, range, and bandwidth (here’s a simple explanation). Choosing which connectivity option is best comes down to the specific IoT application, but they all accomplish the same task: getting data to the cloud.

Data Processing

Once the data gets to the cloud, the software performs some kind of processing on it.

This could be very simple, such as checking that the temperature reading is within an acceptable range. Or it could also be very complex, such as using computer vision on video to identify objects (such as intruders in your house).

But what happens when the temperature is too high or if there is an intruder in your house? That’s where the user comes in.

User Interface

Next, the information is made useful to the end-user in some way. This could be via an alert to the user (email, text, notification, etc). For example, a text alert when the temperature is too high for the company’s cold storage.

Also, a user might have an interface that allows them to proactively check in on the system. For example, a user might want to check the video feeds in their house via a phone app or a web browser.

However, it’s not always a one-way street. Depending on the IoT application, the user may also be able to perform an action and affect the system. For example, the user might remotely adjust the temperature in the cold storage via an app on their phone and some actions are performed automatically. Rather than waiting for you to adjust the temperature, the system could do it automatically via predefined rules. And rather than just call you to alert you of an intruder, the IoT system could also automatically notify relevant authorities.
