Air Quality Sensor Buying Guide
An air quality sensor is an electronic device used to monitor the concentration of pollutants (such as PM2.5, CO2, VOCs, etc.) and environmental parameters such as temperature and humidity in real time. It is widely used in fields such as environmental monitoring, smart homes, and industrial emission control, and can provide data support for air quality assessment and health protection.

Factors of Choosing Air Quality Sensors
When selecting an air quality sensor, it is necessary to comprehensively consider multiple core factors to ensure that it can meet the actual application requirements.
Monitored substances and measurement range
These are the most basic selection criteria. Different air quality sensors are designed for different pollutants, such as PM2.5/PM10 (particulate matter), CO₂, VOCs (volatile organic compounds), formaldehyde, ozone (O₃), etc. Users should select appropriate sensors based on the target detection objects and ensure that their measurement ranges cover the concentration levels in the actual environment. For example, industrial environments may require sensors with higher measurement ranges, while residential environments may prioritize low-concentration detection.
Resolution
This determines the smallest change in pollutant concentration that the sensor can detect. For example, high-precision formaldehyde sensors may require a resolution of 0.01 ppm. The higher the resolution, the more sensitive the sensor is to small changes, making it suitable for scenarios requiring precise monitoring.
Accuracy or consistency
Directly impacts the reliability of the data. The error range of air quality sensors typically falls within ±5% to 10% (commercial grade) or ±1% to 3% (industrial grade), and long-term stability is also critical to prevent data distortion caused by drift. Some sensors (such as electrochemical or NDIR types) require regular calibration to ensure measurement results comply with standards.
Environmental adaptability
Determines the sensor's performance under different conditions. Temperature and humidity changes (e.g., -20°C to 50°C) may affect the accuracy of certain sensors, while high dust, corrosive gases, or vibration environments (e.g., in-vehicle applications) require air quality sensors with stronger protective capabilities. Additionally, interference resistance is important; for example, VOC sensors should avoid false alarms caused by alcohol or other gases.
In summary, when selecting air quality sensors, it is recommended to prioritize requirements, conduct a comprehensive assessment considering monitoring needs, accuracy requirements, environmental conditions, and other factors to ensure the selected sensors can reliably and accurately provide the required data. It is recommended to review and compare the following sensors from the ATO and related data to efficiently select suitable models.
