Low-cost sensors for outdoor air quality monitor

With the acceleration of urbanization, urban air quality has become a common concern.

Poor air quality has a serious impact on human health and ecological environment.

Poor air quality has a serious impact on human health and the ecological environment. how to measure air quality outside has become the main research object nowadays.

In this paper, we will discuss the principles, functions and applications of Outdoor air monitoring sensors in urban planning and environmental protection.

Principle of Outdoor air quality monitor

The Outdoor air quality monitor assesses air quality by measuring the concentration of pollutants in the environment using a built-in sensor.

The working principle of the sensor is based on chemical analysis technology, whereby the interaction of the sensor material with the pollutants in the environment generates an electrical signal that determines the concentration of the pollutant.

Regardless of the type of industry chain, gas sensors are indispensable. Sensor technology makes it easy to collect accurate data in all types of situations and to make decisions and take countermeasures quickly. Among them, PM2.5, PM10, SO2, NO2, CO, O3 and other gases environmental monitoring sensors are widely used in atmospheric environment monitoring.

Common sensors used in Outdoor air quality monitor include gas sensor, particulate matter sensor and optical sensor.

Functions of Outdoor air quality monitor

  1. Real-time monitoring: Outdoor air quality monitor is able to monitor the concentration of pollutants in the environment in real time.

Through the collection and analysis of real-time data, city managers can understand the trend of air quality changes and take timely measures to improve air quality.

  1. Data transmission: Outdoor air quality monitor can transmit the collected data to the central database through wireless network.

In this way, city administrators and the public can access the air quality data anytime and anywhere and act accordingly.

  1. Multi-parameter monitoring: Outdoor air quality monitor can monitor a variety of pollutants at the same time, such as nitrogen dioxide, ozone, particulate matter and so on.

In this way, city managers can have a comprehensive understanding of the overall status of urban air quality and take targeted measures.

Application of Outdoor air quality monitor in urban planning

  1. Urban planning decision-making: Outdoor air quality monitor can provide accurate air quality data to help urban planners make reasonable urban planning decisions.

For example, in the process of urban construction, appropriate building density and greening rate can be determined based on air quality data to reduce pollutant emissions and improve air quality.

  1. Environmental monitoring: Outdoor air quality monitor can be used for environmental monitoring to detect and solve environmental pollution problems in time.

For example, deploying sensors around industrial areas can monitor industrial emissions in real time and take timely measures to reduce pollutant emissions.
