Pollution detection (VISIBILITY)

This is a single sensor solution for measuring NO2, CO and visibility in a road traffic tunnel, rail tunnel or other confined spaces. These measurements and processes are used as part of an air quality management system for ventilation control and monitoring or secondary smoke detection. The IVS2 series visibility detection sensor is a tool for measuring the atmospheric extinction coefficient and determining the visual range of the environment. This device measures the atmospheric extinction coefficient or visibility of the environment by sending a light beam with a wavelength of 550nm from one side (transmitter) and receiving it from the other side (receiver) and calculating the amount of energy received. The electrochemical sensors built into the ECG1 series can also measure the amount of NO2 and CO gases in the environment. IVS2 series sensors are capable of measuring the field of view with high accuracy in the range of 10 meters to 10 kilometers and convert the obtained information into standard current, voltage and RS485 outputs for use. The most important applications of this device include determining the visibility level on highways and airports and the level of pollution and visibility in tunnels, which are vital in reducing energy consumption (permanent use of projectors and air conditioners) and increasing safety. General applications: Measuring the field of vision in various weather conditions such as fog, dust, smoke, snow and rain. Can be used in meteorological organizations, shipping, aviation and road industries to issue visibility warnings. Can be used on roads, passes, bridges and tunnels to adjust the timing and also the level of ambient lighting and ultimately save energy consumption and increase road safety. General features: Compact and lightweight structure. Very resistant body. Equipped with hydrophobic lenses (nano technology). Very low power consumption. Ability to send warnings to smart road signs. No disruption of operation due to ambient light. Maximum error of 5%. Ability to operate at a maximum wind speed of 60 m/s. Ability to automatically control the road lighting system and ventilation systems. Use of a light source with a wavelength of 550nm.
