Problem Overview

To ensure our products meet the highest quality standards, we conduct specific stages of the manufacturing process in cleanroom environments. These controlled conditions help maintain the precision and cleanliness required for critical production steps.

cleanroom Air Monitoring Approach

To track particle levels in cleanroom air over time and adjust production schedules accordingly, we aimed to implement a reliable solution for measuring air quality at defined intervals.

By analyzing the collected data statistically, the goal is to trigger preventive actions before particle concentrations rise to critical levels.

This proactive strategy not only helps minimize particle contamination but also reduces the runtime and workload of air filtration systems — ultimately lowering energy usage and operational costs.

Implemented Solution

To enable thorough monitoring of particle concentrations throughout the cleanroom environment, particle sensors were installed at key locations — including the airlock, the cleanroom itself, and the cleanroom workstation. Sensor data is transmitted through an IoT gateway.

Leveraging edge computing capabilities, the gateway processes the incoming data locally and displays it graphically in real time via its built-in web interface on an LCD screen. This setup provides immediate insight into particle concentration (measured in µg/m³) and visualizes trends over time for each monitored zone.

Additional Features and Remote Monitoring

An external signal tower light provides a clear visual cue for personnel by illuminating whenever particle levels fall outside predefined thresholds — instantly indicating whether current air quality conditions are suitable for production.

Thanks to a secure connection to a cloud platform, sensor performance, measurement data, and gateway readings can also be monitored remotely from anywhere in the world.

All recorded data can be effortlessly exported in common file formats and, if needed, distributed automatically via email.
