review

MINI OFSIt is a low-priced visibility detector. It has a wide range of applications, such as being used for fog warning systems.

MINI OFSThe operating temperature should be several degrees higher than the ambient temperature in order to remove water vapor.

MINI OFSBuilt in membrane ventilation device to maintain consistent pressure inside and outside the instrument and keep the circuit dry.

This detector is approximately facing forward25 cmSensitive to fog droplets that affect atmospheric visibility in distant areas. These droplets are generally small water droplets, but they can also be snowflakes, raindrops, or air pollutants. In most cases, low visibility is caused by fog or snow.

output

Analog Output

The microprocessor directly controls the visibility simulation output (such as visibility of)1KMWhen, the voltage is1VThe visibility is500When measured in meters, the voltage is0.5V(And so on). If the receiver is saturated (such as reflected light caused by sunlight or insect snowfall covering the front end of the sensitive area), then the output voltage is5V.

Digital Output

The calculated visibility value isASCIIThe form of the code string isRS232Port display（1200 baud 8N1）,And every30Transfer once per second.

These data strings can be accompanied byRS232The data logger of the port can receive it, or it can be installed with terminal software (such asHyper TerminalofPCreceive.
