In this article, we review the 7 most frequent pitfalls observed in the field—and share practical tips to avoid them from the design phase onward.
1. Failing to check actual ATEX certification
Not all sensors are created equal. Some devices marketed as “ATEX compatible” don’t actually comply with European standards (e.g. EN 60079). It’s essential to check the risk classification (Zones 0, 1, or 2), ask for compliance certificates, test reports, and detailed component information. In the event of an inspection or incident, missing documentation could expose the operating company to serious liability.
2. Neglecting wireless communication and signal quality testing
In complex industrial environments—metal structures, thick walls, interference—wireless signal performance can quickly degrade. Many projects fail due to the lack of real-world range tests and proper network simulation. Whether using LoRaWAN, NB-IoT, or other protocols, network architecture must be considered from the design phase.
3. Using a non-sovereign or non-EU cloud hosting without assessing the risks
Data collected in ATEX zones is often sensitive. Hosting it on non-EU cloud platforms or services lacking legal clarity can raise sovereignty issues, GDPR compliance concerns, and risks of technological dependency. Choosing sovereign or locally hosted infrastructure is generally a safer path.
4. Overlooking active infrastructure monitoring
Even with certified ATEX IoT sensors, if there’s no network monitoring or alert system in place, a failure can go unnoticed for days. An IoT project without visibility is a blind spot. Monitoring should be part of the project from the start—with tools for visualization, redundancy, and real-time alerts in case of connectivity issues.
5. Forgetting to train and involve field teams
Technology alone doesn't guarantee success. Too often, sensors are deployed without training technicians or involving maintenance teams. The result: resistance, poor data usage, and limited responsiveness. A successful IoT project also depends on team buy-in and day-to-day adoption.
6. Lacking clear data governance
Who can access the data? With what permissions? For how long? These questions are often glossed over, creating legal or operational gray areas. Every IoT project should include a structured data governance plan: access rules, data lifecycle, archiving, and traceability. Chances are, your IoT deployment isn’t the first industrial IT initiative on site—so it should either fit into existing governance frameworks or help evolve them.
7. Treating cybersecurity as a one-off effort
Cybersecurity isn’t something you “set and forget” at launch. It requires regular updates, audits, vulnerability management, network segmentation, and disaster recovery planning. In a high-risk environment like ATEX, an exposed IoT sensor can become a critical entry point for cyber threats.
Getting It Right: the right technologies, the right processes
The success of an IoT project in ATEX zones depends not only on choosing the right technologies, but also on avoiding common missteps. Certification, testing, cybersecurity, data governance, and user adoption are the foundations of a reliable and sustainable deployment.
By anticipating these issues, you strengthen your safety, efficiency, and industrial reliability.
