Introduction
Hotels face a constant challenge: maintaining guest comfort while controlling energy costs. PIR sensors provide an effective solution, detecting occupancy and automatically adjusting room settings when guests are present or absent.
Key Requirements for Hotel Sensors
1. Energy Savings
Occupancy-based HVAC and lighting control can save 20-30% on guest room energy.
2. Guest Comfort
Sensors must not turn off lights or HVAC while guests are in the room.
3. Privacy
PIR sensors detect presence only, preserving guest privacy.
4. Integration
Sensors must work with property management systems (PMS) and room controllers.
5. Aesthetics
Low-profile, discreet sensors that match room decor.
