Traditional HVAC operates on fixed schedules, conditioning spaces regardless of occupancy. Occupant-centric control responds to actual building use, adjusting temperature and ventilation based on presence and CO₂ levels. This responsive approach helps reduce energy waste from conditioning empty spaces.

Deliver healthier spaces through precise sensing
Monitor temperature, humidity and CO₂ in near real-time to help maintain comfortable indoor conditions for occupants.
Monitor temperature, humidity and CO₂ in near real-time to help maintain comfortable indoor conditions for occupants.
Comprehensive Monitoring for Occupant Comfort
Temperature fluctuations, inconsistent humidity and CO₂ levels all impact the well-being and productivity of people in your building. Environmental sensing provides the detailed data you need. Continuously monitoring key parameters gives visibility into your indoor environment and supplies data to help building automation systems make intelligent adjustments that help improve comfort and reduce energy waste.
Indoor environmental quality (IEQ) monitoring
The TR50 multi-parameter sensor tracks temperature, relative humidity, CO₂, particulate matter (PM1.0, PM2.5, PM10) and total volatile organic compounds in near real-time.
Communication via Modbus, BACnet, and Sylk protocols
Monitor CO2 with ±50 ppm accuracy from 400-5000 ppm
Minimal recalibration and remote firmware updates
Optional local display for on-site verification
Adaptive HVAC and airflow control for energy savings
Demand-control ventilation modulates outdoor air intake based on measured CO₂ levels rather than fixed ventilation schedules, helping to reduce energy consumption without compromising indoor air quality.
CO2-triggered fresh air modulation
Integration with existing BMS controllers
Remote monitoring and diagnostics
Occupancy‑integrated environmental adjustment
Environmental monitoring and control systems can adjust HVAC, lighting and ventilation output based on current occupancy data and usage patterns rather than predetermined time schedules.
Zone-level occupancy detection integration
Automated setpoint adjustments per zone status
JADE economizer for cooling with outside air
Centralized dashboard for multi-site monitoring

Frequently Asked Questions About Environmental Sensors
Environmental sensors provide near real-time data to your building management system via open protocols like Modbus or BACnet. Your BMS uses this data to automate ventilation adjustments. CO₂ sensors support demand-control ventilation by modulating fresh air intake based on actual occupancy levels rather than fixed schedules, helping balance indoor air quality with energy efficiency.
CO₂ sensors enable demand-control ventilation, adjusting fresh outdoor air based on actual CO₂ levels rather than fixed rates. As CO₂ rises with occupancy, the system increases fresh air intake. When spaces are lightly occupied, the system reduces ventilation to help minimize energy consumption. Honeywell's self-calibrating CO₂ sensors are designed to meet California Title 24 requirements.
Discover how to help create healthier, more efficient spaces for your occupants.
