Detect Pollutants with Air Quality Monitoring Systems

Air quality monitoring falls under the umbrella of environmental monitoring, encompassing the collection and analysis of data samples about various chemical conditions such as PM10, carbon monoxide, nitrogen dioxide, ozone, and sulfur dioxide. Additionally, temperature, mold growth, and humidity are also monitored.

The location of air quality monitoring systems is contingent upon the monitoring objectives. For instance, most air quality monitoring systems are dedicated to safeguarding public health and therefore require monitoring stations to be strategically positioned in densely populated areas, particularly near known pollution sources such as busy roads and city centers. However, in some cases, air quality monitoring systems are established to determine baseline pollution levels. In such instances, they are situated away from urban areas and emissions sources.

Benefits

  • to catch problems early before they cause long-lasting damages

  • to facilitate environmental planning methods

  • to automatize data reading and collection

  • to reduce maintenance and operations costs

  • to improve life quality

Air quality monitoring can be conducted:

  • both indoors and outdoors

  • at regular sites (fixed stations) on a continuous basis

  • at selected sites on an as-needed basis

  • on a temporary or seasonal basis

  • at random sites throughout an area

  • on an emergency basis

Air Quality Monitoring Systems and SHM Applications

Furthermore, air monitoring systems play a crucial role in assessing the external factors affecting a structure. To achieve this, various air parameters such as wind, temperature, humidity, etc. are of utmost importance and can be viewed as an extension of a structural health monitoring (SHM) system.

Typically, air quality monitoring systems consist of sensors, data acquisition systems (data loggers), data transfer systems, data management systems, and data analysis tools. Analyzing data can provide valuable insights to accurately interpret changes in air quality. This identification allows for targeted pollution prevention programs.

Air Quality Monitoring Systems with IoT Technology

The Internet of Things (IoT) technology is particularly well-suited for such applications, as it is capable of managing large volumes of digital data. Moreover, IoT facilitates real-time and remote access, collection, and analysis of data. Consequently, it eliminates the need for on-site field inspections involving human workers.

Through remote data acquisition using IoT technology, valuable information can be obtained for structural health monitoring applications, specifically for air monitoring systems. This enables efficient pollution detection and assessment.
