Air Quality Sensors
Intelligent Air Quality Sensors for HVAC Systems — Precision IAQ Monitoring
Belimo air quality sensors play a vital role in ensuring healthy and comfortable indoor environments while supporting energy-efficient building operations. These advanced sensors—including CO₂ and VOC (volatile organic compound) models—are designed to continuously monitor indoor air quality (IAQ), helping facility managers maintain optimal ventilation and occupant comfort. By detecting changes in air composition, Belimo sensors enable dynamic control strategies that reduce energy consumption without compromising air freshness.
In addition to standalone air quality sensors, Belimo also offers integrated solutions that combine temperature and humidity sensing in a single device. This multi-functionality simplifies installation, reduces wiring complexity, and enhances system performance. Whether used in commercial buildings, schools, or healthcare facilities, Belimo’s air quality sensors contribute to smarter, more responsive HVAC systems that promote well-being and sustainability.
