FAQs

What is a visibility sensor?

A visibility sensor is a device used to determine air clarity and the distance objects can be seen. It calculates the actual visible distance by emitting a beam of light and measuring the degree of scattering that occurs when the light encounters fog, smoke, dust, rain, or snow in the air. The cleaner the air, the less the light is disrupted, resulting in higher visibility; conversely, visibility decreases as air quality deteriorates. This equipment is commonly used in roadways, airports, ports, and meteorological monitoring to provide reliable data for safety alerts and environmental observation.

how do visibility sensors work

XF-CQ10 utilizes the principle of forward scattering optics to measure the scattering intensity of light beams by particles such as smoke, dust, haze, rain, and snow in the air. It calculates atmospheric transmittance to obtain real-time visibility data. Combined with ambient light suppression algorithms and temperature/humidity compensation, it achieves high-precision measurements.

How do they measure visibility?

Visibility measurements are typically based on the principle of forward scattering optics: a sensor emits a beam of light into the air, which is scattered when it encounters particles such as smoke, dust, haze, rain, or snow. The receiving unit measures the intensity of the scattered light; the more particles present, the stronger the scattering, and the lower the visibility. The system then combines a transmittance calculation model with an environmental compensation algorithm to convert the scattered signal into a standard meteorological optical range (MOR), thereby obtaining an accurate visibility value.

Can this device be used in extreme environments?

Yes. The XF-CQ10 features an IP65+ rated enclosure, corrosion-resistant housing, and an optical heating defogging design, enabling long-term stable operation in harsh conditions such as high humidity, extreme cold, sandstorms, rain, and snow.

What’s the common power supply and signal output?

Common power supply and signal output is DC: 12VDC, RS485. The other demand can be custom made.

What should I do if there is no communication or abnormal data?

No communication: Check the power supply, cables, and communication configuration parameters.
Abnormal data: Check if the sensor is contaminated by foreign objects, if there are reflective surfaces nearby, or if there are infrared-emitting devices (such as infrared cameras) in the vicinity.
