Environmental sensors can provide an accurate picture of air quality, helping the authorities take the required steps just in time.
Air cleaning towers are a common
sight in cosmopolitan cities. Since they can be used to fight smog during the
winter, it is also called smog towers. But, of late, the efficacy of these
towers has come into question. They are rendered defunct due to excessive
operations, even when they are not needed. NEC India has developed environment sensors
that can detect the level of pollutants and particulate matter so that these
air cleaning towers can be activated at the right time.
Smog towers are supposed to suck
in air using a downdraft air-flow model and over 5000 filters. They have the
capacity to purify 1000 cubic meters of air per second. But, it is necessary to
have efficient environment sensors to ensure authorities have accurate data on
the level of particulate matter in the air.
A smart city will be able to use
air-cleaning towers more efficiently if it has environmental sensors. These environmental sensors can detect and display
the level of PM2.5 and PM10 on LED screens.
The IT solution provider has leveraged environmental sensors to ensure sustainability in urban areas like Dombivli in Mumbai and Saharanpur City in Uttar Pradesh. Environmental sensors are part of a broad range of smart city solutions, which include smart city operations centers and flood sensors in the city.
Real-time data regarding the
ambient air quality through parameters like the air quality index can help
authorities take urgent steps when the situation worsens. A graded response
action plan, or GRAP, is one of the ways to deal with pollution.
As part of the GRAP, the city can
activate the smog towers when needed, increasing its efficacy. In addition to
this, other steps like using anti-smog guns with dust suppressants can also
help in dealing with pollution effectively.
