Air quality sensors are technological devices that measure various pollutants and weather conditions in the ambient air. These sensors are used to assess the quality of the surrounding air and are generally widely preferred indoors and outdoors. Increasing air pollution, especially in large cities and industrial areas, has increased the need for such devices.
What Do Air Quality Sensors Do?
Air quality sensors provide information about air quality by measuring various parameters such as harmful gases in the atmosphere (such as carbon dioxide, VOCs), particulate matter (such as PM2.5), temperature, humidity and pressure. Thanks to these sensors, precautions can be taken in advance to prevent health problems caused by air pollution. Below you can find information about some of the basic parameters these sensors measure and why they are important:
Carbon Dioxide (CO2): CO2 is a gas that occurs as a result of human breathing and the combustion of fossil fuels. High CO2 levels can cause fatigue, headaches and loss of concentration, especially in closed areas.
Volatile Organic Compounds (VOCs): VOCs are gases emitted from various chemical substances. These substances, which are released from sources such as cleaning products, paints and construction materials, can cause respiratory problems and serious health problems in the long term.
Particulate Matter (PM2.5): Particles smaller than 2.5 microns in diameter can penetrate deeply into human lungs. PM2.5 is particularly associated with respiratory diseases and cardiovascular problems. Therefore, measuring this substance is critical to understanding air quality.
Temperature and Humidity: The temperature and humidity of the air have a direct effect on comfort levels and health. In particular, excessively high or low humidity levels can trigger allergies and respiratory disorders.
Air Pressure: Changing air pressure can affect atmospheric events and environmental conditions. Sudden pressure changes can have an impact on people's general health.
How Do Air Quality Sensors Work?
Air quality sensors usually have sensor components that work on different principles. For example:
NDIR (Non-Dispersive Infrared): This technology is used specifically for measuring CO2. NDIR sensors use light of a specific wavelength to determine CO2 levels in the air.
Metal Oxide Semiconductors (MOX): These types of sensors are used to detect the presence of VOCs and other gases. When gases come into contact with the metal oxide surface, the electrical properties of the sensor change, and this change is associated with the concentration of the gas.
Particle Measurement Sensors: Laser light and photo sensors are used to measure particles such as PM2.5. These sensors provide information by analyzing the number and size of particles in the air.
Air quality sensors provide a healthier and safer life by allowing people to continuously monitor the air quality of the environments they live in. Whether at home, at work, or outdoors, these devices allow you to breathe clean air and minimize potential health risks. With increasing environmental awareness and technology, air quality sensors are expected to become even more widespread in the future.
