What product do you need? 

While we have many devices which can meet your requirements. Finding the right one that is most suitable and economical is the main issue for a lot of out customers!

In order to recommend the best IoT device, we need to have a general understanding about your project. Below is a list of questions that'll get this process started!

To understand a project, we need basic information such as:
1. Project purpose, for example, what result does end user want to achieve?
2. How many sensors / meters/ instruments are there in field? What are they?
3. What kinds of data / parameter do they output?
4. How do you need to output data? By RS485 serial port or I/O ports? Digital or Analog? This will decide what kinds of ports the IoT device need to have.
5. Where is the server for data? Local server or cloud platform? it support what protocol?
6. Whether cellular communication is a must? Whether ethernet cable communication is acceptable or not?
7. Whether the customer needs to do remote control , or just remote monitoring/ data logging only?

What is PLC Programming?

IoT gateways are a part of the Internet of Things (IoT) concept. They are used to connect a PLC to various systems. Building applications, for example, often have hundreds of sensors and generate a large volume of data. The gateways then send that data to the PLC, which may be able to adjust the air conditioning setting. In addition, they allow other devices to communicate with each other.

Some IoT gateways go beyond route data. They can preprocess, deduplicate, summarize, or aggregate data before sending it to the cloud. These preprocessing functions can reduce response times and network transmission costs. If your IoT system has many sensors, your gateway may be able to process more data than one device at a time. If your gateway can handle this amount of data, you can reduce the number of devices it interfaces with.

Can These Products Provide Monitoring?

The IoT gateway provides a comprehensive monitoring system for IoT devices. Its ability to send and receive messages from sensors in other systems makes it an excellent asset for IoT deployments. However, you should be aware of some important things to keep in mind when monitoring your gateway. For instance, you should monitor the signal level at the gateway and configure it to send real-time alerts when the signal falls below a certain threshold.

If your IoT network is comprised of hundreds or thousands of end devices, you must ensure that they reach the gateway in time. Although robust wireless technology, appropriate planning, and optimal architecture are critical to the smooth functioning of an IoT network, unexpected issues can affect its performance. Using an IoT network monitoring solution can notify your team in real time of any problems that may arise. With this kind of proactive protection, you can avoid a major crisis.

What is a IoT Gateway?

An IoT Gateway is a device, or a software code, that acts as a bridge between an IoT Sensor Network and Cloud Server. Its importance is directly proportional to the number of critical tasks it performs. All devices need to be monitored and therefore have appropriate sensors installed on them, such as temperature, humidity, proximity, and so on. The IoT Gateway manages the connectivity of both IP-based sensors and real-world physical devices.

The IoT gateway contains various communication technologies and connects devices to cloud services. It also enables user-defined applications that manage devices, data, security, and communication. The key benefits of an IoT gateway are described below. These devices offer a variety of immediate benefits. However, they are not suitable for every IoT application. You should be aware of the disadvantages of IoT gateways before you buy one.

What is MQTT?

You can use an IoT gateway MQTT to send and receive messages between devices. The MQTT protocol allows you to exchange messages using the XMPP protocol, which is a standard used by many Internet of Things devices. The MQTT protocol is a popular choice for IoT applications, as it supports both HTTP and RESTful interfaces. The following are several examples of using the gateway MQTT.

The IoT Gateway MQTT Broker is a free client and is available for both Windows and Linux. The IoT Platform is a managed IoT gateway that can manage millions of devices. The MQTT protocol can be used by both the IoT gateway MQTT broker and the Platform Service. The IoT gateways can publish messages of different types with different quality of service levels.

2,Three Reasons to Use an IoT Gateway for Building Monitoring Systems
One of the benefits of an IoT gateway is its ability to monitor all connected devices in a building remotely. This central layer also helps reduce the number of sensors/devices that are connected to the internet. The edge-processing capabilities of an IoT gateway make it even better. Listed below are three reasons to use an IoT gateway. They are listed in no particular order. But, which is best for you?

IoT gateway is a centralized layer within a building...

IoT gateway is an important element for building monitoring systems. These gateways can communicate with devices and the cloud, and they can offer many advantages. For example, they can be lightweight and support new devices easily. Additionally, they offer secure connections to devices and the cloud. They also help reduce the cost of traditional systems. To understand how IoT gateways work, let's look at what they are and how they help building monitoring systems.

First, the IoT gateway acts as a centralized layer within a building management system. It can synthesize and collect data from various devices, such as the HVAC system, the Energy Distribution System, the Biometric System, and the Alarm System. Residential devices could be Day Light Control Systems to save energy, Smart Metering systems, and even smart home accessories. To achieve these benefits, IoT gateways need to support M2M communication between devices.

It can be monitored remotely

If you're concerned about the security of your IoT gateway, you're not alone. Many gateways are vulnerable to attacks, including denial-of-service (DoS) attacks, network traffic spoofing, and jamming. IoT gateways must survive unpredictable power cycles and have the ability to revert to a working state. Security is an important component of an IoT gateway, as it's the first line of defense for any system. Here are three tips to secure your gateway:

IoT gateways have a number of benefits, including a host of security and reliability features. These gateways help mitigate risks and isolate underperforming sensors and devices. Since communications between IoT devices will be conducted over public and private networks, they must be secure. Secure communications require a PKI infrastructure. Digital certificates and cryptographic keys are necessary to protect IoT gateways from malicious attacks. Using an IoT gateway simplifies this process.

It can reduce the number of sensors/devices connected to the internet

IoT gateways reduce the number of sensors/devices that are connected to the internet. Sensors can be hacked to steal personal information or even cause damage. In the case of the Mirai malware, which took down major parts of the internet, this malware affected thousands of connected IoT devices. Gateways act as the first line of defense for connected sensors.

IoT gateways are vital to the overall security of your network. They serve as a bridge between the internet and the devices. Without the gateway, devices would be exposed to the internet. An IoT gateway is a great investment in the future of IoT. The gateway can be an effective way to monitor and maintain the health of your network and reduce the number of sensors/devices connected to the internet.


It can pre-process data at the edge in real time

The development of edge computing is primarily driven by the exponential growth of IoT devices, which connect to the internet to receive and deliver data back to a central cloud. These devices generate huge amounts of data. To make use of this data, edge computing uses a partial framework device to gather and process data locally. The gears are placed in hardened enclosures and are protected from the environment. They analyze and normalize the data stream before sending it back to a central data center.

The third level in the IoT maturity model is pre-processing. In this stage, sensors record an enormous number of data points representing a process from start to finish. Data from these sensors is then analyzed according to the first relevance criteria. Results are then applied to the process in an automated manner. This enables the application of predictive analytics and causal relations. Mobile work machines use edge computing to conduct local analysis and then send data to the cloud for further processing.

It is a prime target for hackers

A recent report by the FBI warns that Internet of Things devices are the prime targets for hackers. These devices serve as gateways for hackers to access and exploit data from other systems. In addition, unsecured devices are ideal targets for criminal campaigns and foreign hackers. Whether they are used to hide or to transmit confidential information, these devices are prime targets for hackers. The FBI report outlines ways to protect these devices from attack.

Because of their high processing power, IoT gateways are prime targets for hackers. They can run more demanding software, making them prime targets for hackers. The downside to these new devices is that they increase the vulnerability of entire IoT ecosystems. While a simple IoT gateway connects to the cloud via Wi-Fi, complex gateways support multiple communication protocols. Some even enable autonomous management of connected devices.
