Air Quality Sensor - All You Need To Know

The air quality sensors are becoming an integral part of the urban landscape. Providing the local community with an updated data on pollution levels is a fundamental of a preventive strategy. How exactly do air quality sensors work, and why is it worth investing in them?
 

When it comes to the prevention of diseases caused by air pollution, providing updated data is the key. Without it, it's impossible for the local communities to judge what level of danger it's facing and when to take protective measures such as antismog masks. 

Air pollution is mostly undetectable by human senses, particularly when it comes to tiny, odorless particles measured in micrometers. This unit serves to define the size of bacteria and human cells. No wonder why inhaling particulate matter can have such implications on our health - they're so small that they can get into the bloodstream through our respiratory system and reach organs, where they accumulate. 

That explains why spreading consciousness and providing the communities with easily accessible information plays such a crucial role in the prevention. And doing that couldn't be any easier with the air quality sensor. Not only locals can benefit from such investment - the device becomes a part of a worldwide network, providing updated data from a particular region 24/7. Airly.org offers air pollution sensors that send the collected information to the server. Thanks to that, it's possible to access it through the app or browser anytime.

How Does the Air Quality Sensor Work?

The air quality sensor measures the levels of various types of air pollution. The accuracy of these measurements depends mainly on the method used by the device. Airly.org, for example, combines the laser method with an electrochemical one. That enables the precise definition of each type of air pollution level.

The laser method serves for detecting particulate matter, and the other one - to measure the concentration of toxic gases. 

The air pollution sensor can verify the levels of:

• PM 2.5 and PM 10
• Carbon Monoxide (CO)
• Sulfur Dioxide (SO²)
• Nitrogen Dioxide (NO²)
• Ozone (O³)

Aside from the polluting particles, it also measures humidity, barometric pressure, and temperature, providing you with a complex set of information.

To transfer the data into the server, the device uses a GSM protocol. This way, the real-time information can be displayed in the app or browser. The users can check the particular region or look through an interactive map. It's an easy way to compare the pollution levels that can serve as a foundation for analysis, too.

How Can the Local Community Benefit from the Air Quality Sensor?

The level of air pollution within the area of one municipality can vary significantly. Providing the inhabitants of every neighborhood with updated data on the PM and toxic gas levels is crucial for a healthier future. This way, the community can monitor the air quality and know when to wear a mask. Air pollution is, in most cases, an invisible enemy - and data is the best weapon against it.
