Is anyone still here?
True Occupancy provides a more dependable occupied / vacant signal during quiet activity.
Occupancy Ratio-Based Room Automation
Make every room respond to who is there, how many people are present and whether the indoor environment is comfortable.
Room-level sensor data can be made available to the BMS or local control layer, where project-defined logic determines the required lighting, ventilation and HVAC response.
Room Demand
A schedule knows the time. It does not know the room.
Rooms change throughout the day. A person may be present but still. A meeting can grow from two people to ten. CO₂ can rise before discomfort becomes obvious.
How many people are here?
People Counting adds anonymous headcount and room-use data.
Is the room comfortable?
IAQ sensing shows when ventilation and environmental conditions need attention.

The lighting and airflow effects are illustrative. Control logic, priority level and data value can be configured according to project requirements and BMS strategy.
Three Signals that Define Room Demand
Presence tells the system when. Headcount tells it how much. IAQ confirms whether conditions are right.
Vital movement · Maintained
True Occupancy
Know when the room is still genuinely occupied.
Micro- and vital-movement detection provides a more dependable occupied / vacant signal during quiet activity, helping the control strategy maintain comfort while the room is in use and apply setback only after vacancy is confirmed.

People Counting
Know how much demand the room is creating.
Anonymous headcount and occupancy ratio-based data show how much demand a room is creating, helping the BMS scale ventilation, fan speed and terminal-unit response to actual use.

Indoor Air Quality
Confirm whether room conditions remain appropriate.
CO₂, temperature and humidity show whether room conditions remain appropriate, helping the BMS adjust ventilation, coordinate HVAC operation or raise alerts against project-defined targets.

From Room Sensors to Building Control
01
Sense
Presence, people count and IAQ data are captured inside the room.
02
Connect
Data travels through the supported wired or wireless communication route for the selected devices.
03
Integrate
A gateway, controller or compatible interface makes the required data points available to the BMS.
04
Respond
The BMS or local controller applies the commissioned logic to lighting, ventilation, HVAC and alerts.
Room-level data is collected by the selected sensors and made available to the BMS or local control layer through the project's supported integration route. The BMS or local controller then applies the agreed control logic, while available data points, protocols and functions depend on the selected devices and project configuration.
Spaces with Changing Room Demand
Designed for spaces that never stay the same for long.
Meeting rooms
Headcount and CO₂ help ventilation and cooling respond as attendance changes.
Offices
True Occupancy distinguishes quiet work from vacancy, helping comfort remain available while the room is still in use.
Classrooms
Presence, headcount and IAQ help the room respond across lessons, breaks and changeovers.
