20km portable visibility detector

20km portable visibility detectorTraffic Management: In scenarios such as highways and mountainous roads, real-time visibility information is provided to assist transportation departments in adjusting speed limits, activating fog induction systems, or closing dangerous sections. When the visibility is below the threshold, the system automatically triggers warning lights and broadcasts reminders to reduce the risk of traffic accidents. Air traffic is used for runway visual range (RVR) measurement at airports to ensure the safety of aircraft takeoff and landing. Meteorology provides accurate visibility data for meteorological departments, supports weather forecasting and meteorological research, and helps to early warn weather phenomena such as haze, sandstorm, rainstorm, etc. Environmental protection is an important indicator for measuring air quality, and visibility monitoring provides data support for environmental protection departments to assist in assessing air quality conditions, monitoring industrial emissions, and urban pollution.
