Tunnel Monitoring

smart/ECS Multi Gas Sensor

An IoT-enabled gas sensor that can detect up to four gases: (CO, NO, NO₂, SO₂ - other gases on request)

Photometer for measuring the illuminance at the sensor mounting location (in-situ)

Measuring luminance - the perceived light available for drivers to drive safely - the main control variable for the tunnel lighting.

Measuring tunnel air flow by differential pressure.

Precise ultrasonic air flow measuring system based on different transition times of ultrasonic pulses

Monitoring of traffic signal states in front of and in the tunnel

Extractive Visibility and Gas Monitoring System with all important components located outside of the tunnel.
