SAQ Roads

The Sentinel station for roads and Intelligent Transportation Systems (ITS) is a monitoring solution specifically designed for transportation environments. It features high-precision sensors capable of measuring particulate matter (PM1, PM2,5, PM4, PM10), and key traffic-related gases such as NOx, O3, NH3, TVOC, providing accurate real-time data to ITS.

Housed in a robust, weatherproof enclosure, it ensures reliable operation under all roadside conditions. The station’s seamless integration into ITS networks and its user-friendly interface facilitate effective traffic management, pollution control, and enhanced environmental safety. By delivering critical air quality information, this station helps to improve urban planning, reduce emissions, and protect public health along busy roadways.

The Sentinel station comes as standard equipped with radar for vehicle tracking and classification, noise sensor and can be optionally equipped with full meteorological solutions from the Observator Instruments portfolio.
