The XF-CQ10 forward scatter visibility sensor for road employs an optical measurement principle to monitor atmospheric road visibility in real time, providing precise data for highways, bridges, tunnels, and Road Weather Information Systems (RWIS). The device features a wide measurement range, high-precision output, and an RS485 communication interface; it also incorporates low-power heating capabilities and is designed to withstand harsh environmental conditions, making it suitable for applications such as intelligent traffic management, traffic safety early warning systems, and environmental monitoring.
