Enhancing Indoor Climate Monitoring and Access Control in the Amsterdam Metro

The Project

In the Amsterdam Metro, ensuring a safe and well-monitored underground environment is crucial. The goal was to measure the indoor climate within underground stations, monitor door access to control presence in restricted areas, and achieve a highly reliable signal reception. Given the complexity of operating in a subterranean setting, the solution needed to be both robust and adaptable to the existing infrastructure.

 

 

The Problem

Retrofitting cabled hardware and sensors in an underground metro system is costly and impractical. The aging infrastructure was not designed to accommodate modern access control systems, making it difficult to monitor restricted exits effectively.

 

The underground environment also posed challenges for maintaining a stable indoor climate, and existing wM-Bus sensors required a unified system for data collection. Additionally, there was a need to continuously measure CO₂ levels in office spaces every four minutes while maintaining a high service level agreement, even in hard-to-reach locations.

 

 

The Solution

The implementation of mioty wireless sensors from Lansen provided a highly efficient and scalable solution. The system included door and window sensors, presence detectors, and CO₂ sensors, all communicating through a Wittra unified mioty Gateway. With this setup, it became possible to accurately monitor door status, detecting whether they were truly open or closed, and track human presence using occupancy detectors. Air quality, noise levels, and CO₂ concentrations could now be measured with precision. The system ensured a high reliability of signal reception, even in the challenging underground metro environment, while also providing real-time asset status reporting for enhanced operational control.

 

 

 

The Results

By utilizing mioty technology, the project achieved high reliability of data reception, ensuring uninterrupted monitoring in the demanding conditions of a subway system. The real-time asset status reporting provided up-to-date insights into door access, air quality, and occupancy. The full integration of mioty sensors and gateway allowed for a seamless and future-proof solution, offering:

 

• interoperability
• ease of use
• long-term sustainability for future technology developments.

 

With this implementation, the Amsterdam Metro successfully modernized its monitoring capabilities, improving both security and environmental conditions underground.
