What is IoT?
Nowadays, people have started making everything ‘smart’ – smartphones, smart watches, even smart houses! Behind all this is a fascinating concept: often referred to as the Internet of Things (IoT). The Internet of Things is no more hype; it is a reality that is changing the world with the help of technology. In this blog, we will be walking through various areas of IoT such as Communication, the layers, access and IoT control panels.
IoT Communication Protocols
The IoT devices interact through the use of protocols to enhance the interaction that happens between them. Here are some popular IoT communication protocols: Here are some popular IoT communication protocols:
1. MQTT (Message Queuing Telemetry Transport):
A lean version of the protocol suitable for areas that frequently experience low, or intermittent connectivity.
It is used when the devices are texting in real-time, and they relay through a broker.
2. CoAP (Constrained Application Protocol):
This is specifically built to work with low-power devices which are typical with IoT applications.
A protocol that is a lighter version of HTTP ideal for devices with less power capabilities.
3. HTTP/ HTTPS:
There are also, web communication protocols typically used in IoT applications.
HTTPS enhances security, which is very essential in IoT settings.
4. Bluetooth and BLE (Bluetooth Low Energy):
Suits a situation where the message or information is to be conveyed within a very short range such as in the office.
Recently used in smart items of clothing and home appliances.
5. Zigbee and Z-Wave:
These are low-power mesh network standards that are now in use in Smart Home devices.
These permits the connection of one device to another and also create a stable network.
Understanding IoT also involves knowing its different levels, which can generally be categorized into four main categories: Understanding IoT also involves knowing its different levels, which can generally be categorized into four main categories:
1. Device Level:
This level is the least complicated and contains the simple sensors and actuators that are used in data acquisition or for actions.
Data is produced mainly at this step.
2. Connectivity Level:
At this level, the devices have the ability their pass data to and from the networks by applying various protocols.
The communication is done through protocols such as Message Queuing Telemetry Transport commonly referred to as MQTT, constrained application protocol commonly referred to as CoAP or Hypertext transfer protocol commonly referred to as HTTP.
3. Edge Level:
At Edge level data analysis takes place either by the edge device or the gateway.
This increases the probability of attempts and the production line capacity to handle those attempts
4. Cloud Level:
Is related to the processing of extensive databases.
Information is kept most often on remote servers and cloud storage on which sophisticated biometric analysis and machine learning operations are performed.
Security is an important topic whenever we are dealing with IoT devices. These involve measures that enable only the right users to have the right uses for the devices. Important components of access control include:
1. Authentication:
The identification of users is also very crucial in our case because it will help ensure that only accredited persons can control the gadgets.
This can be passwords, fingerprint scanning, or even the use of tokens in what is referred to as two-factor identification
2. Authorization:
Once it is authenticated, then be given certain privileges to perform certain actions.
What it means is that a few users can only read data while others can control connected devices.
3. Data Encryption:
Transmitting data in an encrypted form makes it impossible for any other person to access it and thus must be implemented.
This ensures the safety of sensitive information.
4. Regular Updates:
An IoT device cannot escape frequent updates as a security measure against various threats.
IoT Control Panels
Some of the features that lie within an IoT control panel include the management of devices. These panels typically offer several features:
1. Device Management:
The connected devices can be easily added or removed or configured it easily by its users.
2. Real-time Monitoring:
Users can easily track the device’s performance through its control panels and get real-time data and status updates.
3. Automation:
Automation can be created so that two devices can automatically perform a set action (for instance, smart lights switch on during a certain time).
4. Notifications:
Control panels also can notify users with alerts or any relevant events or problems.
