Home All In One RS485 IAQ Smart Air Quality Monitor For HVAC BMS

All-in-One IAQ Monitor with Smart Output Control for HVAC/BMS

Optimize indoor air quality with the All-in-One IAQ Monitor, purpose-built for seamless integration with HVAC systems and air purifiers. This smart sensor offers real-time monitoring of key air quality parameters — including CO₂, PM2.5, PM1.0, TVOCs, temperature, and humidity — and automatically triggers connected equipment to maintain healthy, comfortable environments.
With built-in relay and analog output controls, the IAQ monitor can directly activate ventilation, purification systems, or alarms based on customizable air quality thresholds. Whether for smart homes, office buildings, schools, or medical facilities, this device ensures responsive, automated control for optimal air management.
Key Features:
Multi-Parameter Sensing: Monitors CO₂, particulate matter (PM2.5/PM1.0), TVOCs, temperature, and humidity
Smart Output Control: Integrated relay and analog (0–10V / 4–20mA) outputs for direct equipment control
HVAC & Purifier Integration: Automatically operates ventilation or filtration systems based on real-time IAQ readings
Modbus RS485 Communication: Supports integration with BMS, HVAC controllers, and automation systems
24V Power Compatible: Easily fits into existing building power infrastructures
Optional LCD or Touchscreen Display: Clear visualization of real-time air quality data and output status
Custom Threshold Configuration: Set action points for each parameter to trigger outputs precisely when needed.
