Honeywell IAQ sensors connect to building management systems through open protocols including Modbus, BACnet and Sylk. This system-agnostic approach enables integration with Honeywell controllers and third-party BMS platforms. Sensors expose data points for CO2, particulate matter, TVOC, temperature and humidity that controllers can use in HVAC control strategies such as demand-controlled ventilation, filtration optimization and economizer logic. Remote Building Manager and other cloud-based platforms can aggregate IAQ data from multiple sensors across facilities to provide portfolio-wide visibility, configurable automated alerting and trend analysis.

Frequently Asked Questions About Indoor Air Quality
Honeywell IAQ sensors can measure CO₂, TVOC, PM2.5/PM10, temperature and humidity. They can expose data to BMS for DCV, filtration optimization and economizer logic. Some models provide Modbus, BACnet, Sylk and visual status indications.
ASHRAE 62.1 identifies contaminants of concern beyond CO2 alone, including volatile organic compounds like formaldehyde, benzene and toluene, plus particulate matter (PM2.5), carbon monoxide, ozone and ammonia. The TR50 multi-parameter sensor addresses this by monitoring CO2 for occupancy-based ventilation, PM2.5 for particulate contamination, TVOC for off-gassing from materials and furnishings, plus temperature and humidity for thermal comfort and moisture control. Humidity in the 40-60 percent range helps reduce airborne virus transmission.
Monitoring multiple parameters provides a more complete picture of indoor environmental quality than relying on CO2 concentration as a proxy.
