How do air pollution sensors work?

Awareness of the disastrous effects of pollution on human health is growing steadily. We are taking a number of measures to minimize the negative effects of long-term smog inhalation. One of them is data tracking. But, are they reliable? How do air pollution sensors work?

Tracking air pollution data

Tracking reliable, up-to-date data allows us to adjust our daily schedules to suit the current conditions. This helps us avoid exposing our bodies to harmful, toxic substances when we don’t need to. But how do we access this data? Many mobile or web apps show numbers that are sucked out of your finger. Trust the companies that make their measurements from technologically advanced sensors. How do air pollution sensors work and why do they provide such good data?

How do air pollution sensors work?

The sensor uses a laser and an electrochemical method to measure the particles in the air. The readings are taken by two cells installed in the sensor’s gas module. Each of them has a special diode whose colors change according to the current air quality. The user, who has the necessary instruction, knows how to read the messages received. Understanding how do air pollution sensors work affects the analysis of data received through them.
