Small visibility sensor recommended

A small visibility sensor is a sensor used to measure visibility. Visibility refers to the farthest visible distance that the human eye can recognize under specific atmospheric conditions, usually measured by the intuitive visibility of the reference object.

Small visibility sensors are usually measured using the principle of laser scattering. The so-called laser scattering refers to the scattering phenomenon generated when the laser encounters particles in the air. The scattered light intensity is related to particle concentration and particle diameter, while particle concentration and particle diameter are related to visibility.

Small visibility sensors typically use an infrared laser as a light source, firing a laser beam into the air. When the laser beam encounters aerosol particles, it scatters and forms a backscattered beam. The sensor measures the backscattered light intensity and calculates the concentration and particle diameter of aerosol particles in the air based on the light intensity. From this data, sensors can calculate visibility.

Small visibility sensors are usually small in size, stable in operation and low in energy consumption. Due to the small size and low power consumption of the sensors themselves, they can be easily integrated into various devices and systems, such as drones, cars, weather towers, etc.

Small visibility sensors can be used in many fields. In the field of transportation, sensors can be used to monitor road visibility in real time and provide real-time road condition information to traffic authorities. In the field of meteorology, sensors can be used to detect current visibility conditions in real time and provide more accurate data for weather forecasts. In the industrial sector, sensors can be used to monitor aerosol concentrations in the air, thereby controlling pollutant emissions during production.

In short, small visibility sensors are an important environmental monitoring device that can accurately measure environmental conditions and provide valuable data for related industries.
