Introduction: Health Lies in Every Breath
Air is invisible, and many harmful pollutants are odorless—yet they profoundly impact our health. Every breath we take may expose us to these hidden dangers. Tongdy's environmental air quality monitors are designed to make these invisible threats visible and manageable.
About Tongdy Environmental Monitoring
For over a decade, Tongdy has specialized in advanced air quality monitoring technologies. Its range of reliable, real-time data collection devices is widely used in smart buildings, green certifications, hospitals, schools, and homes. Known for precision, stability, and international compatibility, Tongdy has formed long-term partnerships with numerous multinational corporations, with hundreds of deployments worldwide.
Why Indoor Air Quality Matters
In today’s lifestyle, people spend about 90% of their time indoors. Poor ventilation in enclosed spaces can lead to the accumulation of harmful gases such as formaldehyde, CO₂, PM2.5, and VOCs, increasing the risk of hypoxia, allergies, respiratory illnesses, and chronic diseases.
Common Indoor Pollutants and Their Health Effects
Pollutant |
Source |
Health Effects |
PM2.5 | Smoking, cooking, outdoor air | Respiratory diseases |
CO₂ | Crowded areas, poor ventilation | Fatigue, hypoxia, headaches |
VOCs | Building materials, furniture, vehicle emissions | Dizziness, allergic reactions |
Formaldehyde | Renovation materials, furniture | Carcinogen, respiratory irritation |
How Tongdy Air Quality Monitors Work
Tongdy devices integrate multiple sensors that continuously track key air quality indicators and transmit data via network or bus protocols to platforms or local servers. Users can access real-time air quality information via desktop or mobile apps, and devices can interface with ventilation or purification systems.
