Tunnel brightness monitor

Tunnel brightness monitor is an efficient lighting control system that accurately measures the brightness of the tunnel entrance and automatically adjusts the internal lighting.The Tunnel brightness monitor can fully meet the requirements of the entire tunnel lighting control. The controller in the preset control mode automatically switches the lighting switch according to the preset parameters according to the light source measurement value, providing the best value for tunnel lighting. Its design fully complies with CIE's requirements for tunnel lighting measurement and can meet the "Highway Tunnel Ventilation Lighting Design Code", and its overall design can fully meet the requirements of harsh working environments in the wild.

Tunnel brightness monitor installation method:

The Tunnel brightness monitor is installed on the walls of the designated area in the tunnel. In order to avoid damage to it by accidents or car wreckage, it must be installed at a height of about 4m and an appropriate position greater than 10m from the entrance of the tunnel. The Tunnel brightness monitor is installed at an appropriate position where the height outside the tunnel is about 4m from the road surface and about 120-200m from the entrance of the tunnel. High reliability and low maintenance. Latest microprocessor technology, fully digitally run, installation

Easy to debug.
