Breathe easier with Milesight IAQ sensors. Our devices continuously monitor critical indoor air factors — including CO2, PM2.5, PM10, TVOC, HCHO, O3, humidity, temperature, light, barometric pressure, and occupancy — providing real-time insights into your environment. By identifying invisible pollutants and unhealthy conditions, you can take timely action to improve comfort, protect occupant health, optimize HVAC performance, and meet green building standards like WELL and LEED.
![co2 co2]()
CO2 (Carbon Dioxide)
Elevated CO2 levels lead to fatigue, headaches, and reduced focus. Cognitive performance declines when CO2 exceeds 1000 ppm, while 400–800 ppm is considered the optimal comfort zone. Maintaining healthy CO2 levels improves productivity, concentration, and overall occupant well-being.
![o3 o3]()
O3 (Ozone)
Ozone can originate from outdoor air or be generated indoors by devices such as some air purifiers, copiers, and disinfecting equipment. As a strong oxidant, elevated ozone levels may irritate the eyes and respiratory system, aggravate asthma, and react with other chemicals to form secondary pollutants. For healthier indoor environments, ozone concentrations should remain close to zero, and 8-hour average levels above 0.05–0.07 ppm indicate the need for increased ventilation and source control.

TVOC (Total Volatile Organic Compounds)
TVOCs are gases emitted from paints, furniture, adhesives, cleaning products, and office supplies. High concentrations can cause eye, throat, and skin irritation, and long-term exposure may impact cognitive performance and overall indoor comfort. Keeping TVOC levels low through proper ventilation and source control ensures safer, healthier, and more comfortable spaces.
![formaldehyde formaldehyde]()
HCHO (Formaldehyde)
Formaldehyde is released from building materials, flooring, furniture, and textiles. Prolonged exposure may cause respiratory issues, watery eyes, and skin irritation. For healthier indoor environments, formaldehyde concentrations should remain below 0.08 ppm. Continuous monitoring and control help identify risks early, enable timely mitigation strategies, and support compliance with green building certifications.
![particulate matter particulate matter]()
PM2.5 & PM10 (Particulate Matter)
These tiny particles can enter the lungs and bloodstream, increasing the risks of allergies, asthma, and long-term respiratory diseases. For healthier indoor environments, PM2.5 levels below 15 μg/m³ and PM10 below 45 μg/m³ are recommended. Real-time monitoring helps you reduce exposure and maintain compliance with WHO IAQ guidelines.
![temperature temperature]()
Temperature
Indoor temperature directly affects comfort, productivity, and energy efficiency. Milesight IAQ sensors continuously monitor indoor conditions to maintain the recommended range of 20°C–26°C. Combined with intelligent HVAC automation, the solution helps optimize climate control, reduce energy costs, and create stable, comfortable environments.
![humidity humidity]()
Humidity
Maintaining the right humidity level is essential for health and comfort. Milesight sensors keep track of relative humidity (RH) in real-time, helping you stay within the 40%–60% optimal range. Proper humidity control prevents mold growth, bacterial spread, static electricity, and dryness-related discomfort, ensuring a better indoor experience for occupants.
![light light]()
Light
Our sensors measure illuminance levels to improve workspace comfort and enable automated lighting adjustments. Real-time light monitoring supports energy-saving strategies when combined with occupancy detection.
![barometric pressure barometric pressure]()
Barometric Pressure
Fluctuations in indoor barometric pressure can affect occupant comfort, air circulation, and overall ventilation performance. Milesight sensors provide accurate pressure readings, helping facility managers optimize HVAC settings and maintain consistent airflow for better breathing comfort.
![pir pir]()
Occupancy (PIR)
With built-in PIR occupancy detection, Milesight IAQ sensors intelligently identify whether a space is occupied or vacant. This data enables dynamic HVAC and lighting control, reducing unnecessary energy consumption while maintaining optimal comfort for building occupants.
