Occupancy Sensing: Understanding Space Utilization

Learn how occupancy sensors drive intelligent building automation, optimizing energy use and occupant comfort through real-time space data

Occupancy sensing represents the foundation of intelligent building automation. By understanding when and how spaces are used, buildings can dynamically adjust lighting, HVAC, and other systems to match actual demand rather than operating on fixed schedules. This data-driven approach can reduce energy consumption by 20-50% while improving occupant comfort and productivity.

Modern occupancy sensors combine multiple technologies including passive infrared (PIR), ultrasonic, and even camera-based computer vision to detect presence, count people, and analyze space utilization patterns. This rich data feeds into building automation systems that make real-time decisions about environmental control and resource allocation.

🤖 Occupancy-Based Automation

Configure intelligent rules that respond to occupancy patterns for optimal energy use and comfort.

IF Room unoccupied > 15 min
THEN Reduce lighting by 70%
IF Room occupied
THEN Set HVAC to comfort mode
IF High occupancy detected
THEN Increase ventilation
IF After hours occupancy
THEN Send security alert
