Details

1. Appearance of Visibility Sensor Product

Visibility sensor (visibility weather phenomenon instrument)

2. Overview of Visibility Sensor Products

Visibility sensors (visibility meter weather phenomenon detectors) provide measurements related to meteorological visibility, rainfall, snowfall and mixed precipitation, etc., and are widely used in weather stations, remote automatic weather stations, and traffic safety in airports, highways, waterways, large ships, etc. field.

3. Functions and Characteristics of Visibility Sensors

1) Real-time, online and continuous monitoring of atmospheric visibility;

2) Digital output interface: RS-232 or RS-485;

3) Ability to automatically determine visibility change trends and monitor its own working status;

4) The power consumption is less than 1W, and it can adapt to a variety of power supply methods to facilitate system integration;

5) In order to ensure the long-term stability of the collector, a watchdog circuit is built-in;

6) It is equipped with lightning protection measures, and its communication interface and power interface are designed with lightning protection.

4. Application Fields of Visibility Sensors

1) Intelligent traffic weather sensing system

2) Intelligent street light control system

3) Visibility monitoring system for highway fog areas and severe weather environments

4) Variable speed limit system in bad weather conditions
