Manufacture of visibility sensors

A visibility sensor is a device used to measure visibility in the atmosphere. These sensors typically use optical techniques, such as infrared light or lasers, to detect the scattering or absorption of light by airborne particles, fog, smoke or other obstacles to determine the degree of visibility. Visibility sensors have a wide range of applications in fields such as meteorology, traffic management, and industrial monitoring, providing real-time data on the state of atmospheric visibility to help people make decisions and take measures accordingly.

Visibility instruments (visibility sensors) provide measurements related to meteorological visibility. The sensors are designed based on the principle of aerosol forward scattering, and are a new generation of meteorological visibility monitoring equipment developed following the transmissive visibility instruments. The sensor can be widely used in weather stations, remote automatic weather stations and transport sectors such as airports, motorways, airways and large ships.

The visibility meter (visibility sensor) consists of light transmitter, light receiver and microprocessor controller and other major components. The transmitter emits infrared pulse light, the receiver simultaneously detects the intensity of the pulse light scattered by the forward scattering of aerosol particles in the atmosphere, and all the measurement information is collected by the microprocessor controller and converted into Meteorological Optical Range (MOR) by special mathematical modelling algorithm.
