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.

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.
