Honeywell- HAQ61 Series IAQ Sensors

  HONEYWELL BUILDING MANAGEMENT SYSTEM HAQ61 SERIES IAQ SENSORS  

FEATURES

• Multi-Parameter Measurement

• Simultaneously monitors five air quality parameters — temperature, humidity, CO₂, PM2.5, and formaldehyde (HCHO) — and estimates TVOC based on HCHO.

• Built-in Modbus Communication

• Uses RS-485 Modbus RTU to interface with building automation systems and upload real-time air quality data.

• Optional Screen Display

• Available in versions with or without a TFT display. The screen version shows six parameters on a split screen and indicates air quality levels visually (e.g. face icons) based on PM2.5.

SPECIFICATIONS

• Power Supply: 110–240 VAC, 50/60 Hz

• Operating Temperature Range: –10 °C to +55 °C

• Humidity Measurement Range / Accuracy: 0–99% RH, ±5% RH

• CO₂ Range: 400–2000 ppm, accuracy ±(50 ppm + 5%)

• PM2.5 Range / Accuracy: 0–999 µg/m³; 0–100 µg/m³: ±15 µg/m³; above 100 µg/m³: ±15%

• Formaldehyde (HCHO) & TVOC Range: 0–999 ppb; 0–100 ppb: ±20 ppb; 100–999 ppb: ±20% of measured value

• Communication Protocol: Modbus RTU, RS-485
