Introduction

IoT (Internet of Things) sensors are one of the key elements of modern industrial automation. Thanks to them, companies can monitor production processes in real time, collect data on machine operation and improve line handling in a way that is not possible with traditional solutions. As a result, productivity increases, the number of breakdowns decreases and the company can compete more effectively in the market. In this article, you will learn about the integration of IoT sensors in industrial production and the benefits you will gain by choosing such an implementation. You will also learn the most important steps to keep in mind when planning a similar solution.

In this text, we focus on so-called 'Integration Queries' - i.e. a practical discussion of the implementation and collaboration of robotic systems, machines and IoT. If you're wondering where to start with the IoT sensor integration process and whether it even makes sense in the context of your company, read on. The article is based on the many years of experience of our company - Michale Automatyka - which specialises in the design and construction of machines, production lines and the implementation of robotic workstations.

Why are IoT sensors the future of industry?

IoT sensors in industry have a special role - they enable the collection of data about every part of the manufacturing process, combining this knowledge into a coherent ecosystem. This data can include:

• Temperature of machinery and equipment.
• Humidity and other environmental parameters (e.g. in the food industry).
• Vibration level (helpful in detecting uneven bearing operation).
• Product quality parameters (use of vision systems).
• Pressure or flow of media (e.g. air, oils and other substances).

Gathering information in real time allows a faster response to anomalies. It also provides the foundation for the application of advanced data analytics (e.g. in the cloud) and the implementation of predictive maintenance. As a result, the company can extend the life of machines, reduce downtime and schedule possible repairs at the most convenient times.

Even more important is the fact that IoT sensors are taking the industrial world one step further towards Industry 4.0. This means much greater flexibility in production - trends, errors or imprecise settings can be spotted in time and adjustments made accordingly. Without continuous monitoring and intelligent analysis, it is difficult to optimise processes this far.

Foundations of integration - from requirements analysis to network infrastructure

Before you start implementing IoT sensors in your plant, take the time to analyse the key points of your production. Here are some steps to include in your implementation plan.

1. Definition of objectives and requirements

First, define in which areas IoT sensors are expected to bring specific benefits. For example, this could be:

• Reduce machine downtime by quickly identifying potential failures.
• Improving the quality of the final product through continuous monitoring of environmental conditions.
• Automation of the logistics and storage process (e.g. in the food industry to ensure the right temperature).

In this step, also think about scalability: will the system grow in line with production volumes or will the breadth of integration remain constant.

2. selection of sensor type and IoT infrastructure

You will find a wide range of sensors on the market, from the simplest temperature sensors to advanced video cameras with real-time image analysis. When selecting, the operating environment and communication protocols are key.

• Wireless sensors (e.g. based on Wi-Fi or Bluetooth Low Energy) - excellent where cable installation is difficult. They are often used within private clouds, guaranteeing greater data security.
• Wired sensors - still the most popular choice in the highly demanding production environment, where communication stability is a priority.
• Advanced vision systems - in situations where stationary quality control is needed (e.g. tanks, packaging, welds).

Correct operation of the entire IoT network requires an appropriate communication layer (e.g. HTTP, MQTT, OPC UA protocols). It will also be important to integrate with MES/ERP systems so that data collected by sensors permeates into production management.

3. selection of software and analytical environment

The raw data is only the beginning. The key is to process them into a form that allows for practical conclusions. In this context, the following are useful:

• Cloud platforms (e.g. private clouds deployed internally within the company).
• Specialist tools for Big Data analysis.
• Artificial intelligence and machine learning algorithms (e.g. for trend and anomaly detection).

A well-designed system will help transform unstructured information into useful business knowledge, which is critical with the whole idea of Industry 4.0.

Step by step - how to properly incorporate IoT sensors into a production line?

Below is a simplified 'roadmap' for implementing IoT sensors in a manufacturing plant.

1. fleet audit

To begin with, it is worth conducting a comprehensive audit of the equipment that will work with the sensors. You need to check where it will actually be beneficial to install the sensors. Sometimes a better result will be achieved by optimising a single critical element in the line than by haphazardly spreading the sensors across the entire hall without a plan.

2. network infrastructure design

The network infrastructure is then designed - this usually involves the placement of industrial routers, switches (switches) or antennas for wireless communication. For large factories, it is important that the network signal reaches every sensor with sufficient bandwidth.

3. installation, configuration and pilot testing

• Installation of sensors at target locations
• Machine integration (wired or wireless)
• Configuration of communication protocols with host systems

It is worth running limited tests (proof of concept) - to check that all IoT sensors are returning the correct data and that it can be immediately interpreted in the MES/ERP system.

4 Data analysis and correction

The next stage is to observe and verify the correctness of the data collected by the sensors. It is important to include tools for visualising the results already at this point, so that possible configuration anomalies (e.g. measurement distortions) can be caught. The corrections made will enable more precise data collection and avoid unnecessary "noise".

5. system scaling

Once we have confirmed that the concept works on a pilot scale, the implementation can be extended to other lines, departments or plants. At this stage, it is also worth training employees to maximise the potential of the sensors and the resulting information.

The most common challenges in integrating IoT sensors

Implementing IoT in industry can be complex and presents a number of challenges. It is worth knowing in advance how to deal with them.

Cyber security

As IoT sensor networks often communicate with cloud systems, the risk of cyber attacks increases. Care should be taken to:

• Software updates and security patches.
• Encryption of data transmission (e.g. SSL/TLS certificates).
• Proactive detection of unauthorised devices on the network.

Interoperability of protocols

Different sensor types may use different protocols (e.g. MQTT, Modbus, OPC UA). As a result, it is necessary to combine multiple standards into a single system, which requires a skilful design of the communication layers.

Scalability

As production increases, the number of sensors increases. IoT systems need to scale in such a way that they do not limit productivity, but support further automation.

Power management in wireless sensors

If you opt for battery-powered sensors, you must take care to minimise energy consumption. A solution could be, for example, a longer sampling interval for processes where real-time monitoring every second is not crucial.

An example of the use of IoT sensors in Poland - an Industry 4.0 perspective

According to market data, the Industrial Internet of Things (IIoT) segment in Poland is growing at a rate of around 20% year-on-year and has already reached a value of around PLN 10 billion. One reason for the growth is the high pressure for optimisation and innovation in Polish manufacturing companies.

• Food industry: Sensors measure temperature, humidity, pressure in cold stores or warehouses, which helps maintain product quality and improves food safety.
• Automotive sector: vibration or temperature sensors installed in key line components prevent unexpected machine failures (e.g. presses, welding robots).
• Aviation sector: Sensor data is used for precise part quality control and raw material condition monitoring.

These implementations include not only mass production, but also niche lines where precision and personalised processes are valued.

IoT sensor synergy with robotics - why does it pay off?

Michale Automation is an official distributor of SIASUN robots, and our experience shows that combining IoT sensors with industrial robots brings a number of benefits. Robots, equipped with smart sensors, can react much faster to changes in the environment and optimise tasks in real time.

For example:

• Welding with robots equipped with temperature and vision sensors allows welding parameters to be adapted to the current state of the material. This reduces the formation of defective welds.
• Packaging - robots 'see' and 'feel' the product thanks to advanced sensor technology. This increases speed and prevents damage to goods.
• Precise product layering (e.g. food farm) - integration into the control system, based on information about shapes, weights and conditions.

If you would like to find out more about possible solutions, take a look at our services page robotisation. You will find implementation examples and tips on how to select the right robots with sensors for your specific production line.

Some practical tips to get you started

1. Plan the pre-implementation audit well

Think carefully about which production or logistics stations present the greatest challenges. Sometimes it's not the whole line that needs monitoring, but specific areas prone to failure.

2. Bet on safety in the first phase

Invest in certified devices and protocols. Many companies put off the topic of security until later, and this is a big mistake. Plan security layers in parallel with sensor deployment.

3. Prioritise your data analysis

Not every parameter is equally important. Determine what you want to measure and what action you will take in the event of anomalous readings. Collecting too much data without an idea can make analyses difficult.

4. think about predictive maintenance

When you integrate IoT sensors with data collection systems, you can largely automate machine maintenance schedules. Vibration, temperature or pressure data is often the first indication of a potential problem.

5. Benefit from the expertise of specialists

Implementing IoT and robotisation is a complex task. It is worth considering working with a company that will guide you through the entire process - from design to installation to system maintenance. W our service and maintenance offer you will find support in maintaining robotic workstations with sensors.

Internal linking - where to look for more information?

The deployment of IoT sensors is sometimes closely linked to different sectors of automation. It is therefore worthwhile for you to also familiarise yourself with some of the solutions we describe elsewhere on our blog and website:

• If you are interested in robotising demanding processes such as welding, visit the page dedicated to
  robotisation of welding and see examples of how sensors can realistically translate into better quality welds.
• If you are betting on packaging automation, you will certainly find inspiration at
  robotisation of packaging.

The above articles show specific implementations in Polish companies and how IoT sensors can work in them.

Key benefits of integrating IoT sensors in industry

It's time for a brief summary of the pluses that you will realistically feel in your facility:

1. Reducing costs
   By continuously analysing machine parameters, you reduce the risk of breakdowns and the costs of unplanned downtime. Sensors also allow you to consume less energy through precise control of, for example, cooling or lighting.
2. Improving the quality of production
   Automatic monitoring of parameters means that you catch defects and process failures more quickly and, as a result, have a higher percentage of A-class products.
3. Productivity gains
   Lines equipped with IoT sensors can automatically adjust the speed of machines according to current demand or the state of raw materials (e.g. saving energy outside production peaks).
4. Access to real-time data
   Remote viewing of parameters and intelligent alerts on potential risks allow you to take immediate corrective steps - whether you are in the office, at home or in another branch of the company.
5. Facilitated maintenance and inspection
   With predictive analytics, maintenance can be carried out exactly when it is needed, rather than according to a rigid calendar. This reduces costs and extends the life of the machines.

Practical conclusions and recommendations

- When starting an IoT implementation, do an initial audit of your needs so that you do not unnecessarily collect data that will not translate into real savings or quality improvements.
- Remember cyber security - even the best sensors won't help if hackers gain unauthorised access to your infrastructure.
- When configuring and scaling IoT sensors, it is worth betting on an experienced partner. It is not only the implementation of the sensors themselves that is important, but also the refined integration with robots and MES/ERP systems.

So how do we put these lessons into practice?
1. Identify hotspots in the process and implement IoT sensors there first.
2. involve the IT team in decisions about communication protocols and cloud environments.
3 Include costs not only for the purchase of sensors and robots, but also for integration, maintenance and possible upgrades.
4 Collect data and test on a smaller scale. Only when you are confident of correct operation, expand the system to the whole plant or further areas.
