Air quality monitoring sensors

New from Videalert, air quality monitoring sensors. The devices feature integrated gas and particulate matter sensors and use the company’s existing infrastructure to send readings in real-time, providing council users with measurements showing the level of pollution in key locations.

Tim Daniels, Sales and Marketing Director of Videalert says: “This new air quality monitoring solution gives councils real-time insight into the levels of air pollution around the clock. It is extremely cost effective and can be specified as part of a new Videalert system, retrofitted to an existing Videalert camera installation or deployed as a standalone device. The sensor generates real-time data on the level of airborne particulates, including nitrogen dioxide and carbon dioxide, providing councils with real-time insight into the impact of enforcement cameras on improved air quality. It will have a significant role to play, particularly when used outside schools as part of a range of measures to protect children’s safety and health from pollution caused by excessive vehicle traffic.”

The device features a particulate matter sensor that uses the latest optical-based technologies and sensor fusion algorithms to sense and count airborne particles from 1-1800µgm³. For reliable operation, the sensor is based on light scattering and is fully glass sealed, protecting the internal mechanism from detrimental atmospheric effects.

The device is designed to integrate with Videalert’s RDS WAN units (processors up poles) to transmit captured sensor data to the company’s digital video platform where it can be ‘visualised’ to show the levels of particulate matter, day and night. This data can also be shared with UTMC style systems to inform and alert drivers via video message screens of high pollution and, if appropriate, re-route the traffic. Data from the sensors can also be blended with enforcement data from CCTV cameras to make the business case for the adoption of moving traffic enforcement restrictions including clean air or low emission zones.
