Smart Indoor Air Quality Meter with Programmable Output Control
Take control of your indoor environment with the Smart Indoor Air Quality Meter, designed to monitor and respond to changing air conditions with precision and efficiency. Featuring programmable output control, this intelligent sensor not only tracks multiple air quality parameters but also actively engages HVAC or ventilation systems based on real-time conditions — making it a powerful tool for building automation, energy savings, and occupant health.
This high-performance IAQ meter monitors CO₂, PM2.5, PM1.0, TVOCs, temperature, and humidity with industry-grade accuracy. Integrated relay and analog outputs allow you to automate responses such as fan activation, air purification, or alarms. Ideal for smart buildings, offices, classrooms, labs, and industrial facilities, it seamlessly connects with BMS and control systems via RS485 (Modbus) or optional WiFi/Ethernet.
Key Features:
Multi-Parameter Monitoring: Accurately measures CO₂, PM2.5, PM1.0, TVOCs, temperature, and humidity
Programmable Output Control: Relay and 0–10V/4–20mA outputs for real-time HVAC or system automation
RS485 Modbus Communication: Easy integration with building management and control systems
Optional Touchscreen Display: Local visualization of live data and adjustable settings
Custom Alert Thresholds: Automatically triggers outputs or notifications when air quality drops
Data Logging (Optional): Track and export historical IAQ trends for compliance and analysis
Ideal For:
Smart building automation and HVAC control
Schools, universities, and public institutions
Offices, retail, and healthcare spaces
Cleanrooms, labs, and production facilities
Energy-efficient air quality management
Smart sensing. Smarter control.
The Smart Indoor Air Quality Meter with Programmable Output Control empowers you to not only monitor your air — but actively improve it, one automated response at a time.
