Visibility Sensor – RS485 Road & Highway Weather Monitoring for Traffic Safety
Improve road safety with accurate real-time visibility monitoring. This sensor is designed for highways and intelligent traffic systems, providing reliable data for fog, haze, and low-visibility conditions.
This visibility sensor is designed for continuous monitoring of atmospheric visibility in road, highway, and traffic management applications. It is commonly integrated into automatic weather stations and intelligent transport systems to provide real-time data on environmental conditions affecting driver safety.
Using optical measurement principles, the sensor detects visibility levels by analysing light scattering caused by fog, haze, rain, or airborne particles. The data can then be transmitted via RS485 (typically Modbus RTU) to control systems, enabling automated alerts, signage control, and operational decision-making.
Built for outdoor deployment, the unit is suitable for installation along highways, tunnels, bridges, and critical infrastructure where visibility conditions must be monitored continuously. Its robust construction supports reliable operation in harsh weather environments.
This sensor is widely used in smart traffic systems, transportation infrastructure, environmental monitoring, and industrial safety applications where visibility is a key parameter.
