Introduction
Accurate presence detection is a key factor in today’s smart buildings — it enables energy-efficient HVAC control, improves comfort, and ensures spaces are used effectively. The OPS305 ceiling-mount ZigBee presence sensor adopts advanced Doppler radar technology to detect human presence even when people remain still. It is ideal for offices, meeting rooms, hotels, and commercial building automation projects.
Why Building Operators and Integrators Choose ZigBee Presence Sensors
| Challenge | Impact | How OPS305 Helps |
|---|---|---|
| Energy efficiency & HVAC optimization | High utility costs due to unnecessary system runtime | Presence sensing enables demand-based HVAC control and energy savings |
| Smart building interoperability | Need for devices compatible with existing ZigBee or BMS networks | OPS305 supports ZigBee 3.0 for seamless integration with gateways and building platforms |
| Reliable presence detection | PIR sensors fail when occupants stay still | Radar-based OPS305 detects both motion and stationary presence accurately |
Key Technical Advantages
-
Doppler Radar Presence Detection (10.525 GHz): Detects the presence of stationary occupants more accurately than traditional PIR sensors.
-
ZigBee 3.0 Connectivity: Compatible with standard ZigBee 3.0 gateways for easy integration into building management systems.
-
Optimized Coverage: Ceiling-mount design provides up to a 3-meter detection radius and about 100° coverage angle, ideal for typical office ceilings.
-
Stable Operation: Reliable performance under -20°C to +55°C and ≤90% RH (non-condensing) environments.
-
Flexible Installation: Compact ceiling-mount structure with Micro-USB 5V power makes installation simple for both retrofit and new construction projects.
Typical Applications
-
Smart Offices: Automate lighting and HVAC operation based on real-time occupancy, reducing unnecessary energy use.
-
Hotels & Hospitality: Control lighting and air conditioning in guest rooms or corridors for improved comfort and reduced cost.
-
Healthcare & Elder Care: Support monitoring systems where continuous presence detection is essential.
-
Building Automation: Provide occupancy data for BMS platforms to enhance energy analytics and operational efficiency.
Procurement Guide for B2B Buyers
When selecting a presence or occupancy sensor, keep in mind:
-
Detection Technology: Choose Doppler radar over PIR for higher sensitivity and reliability.
-
Coverage Range: Ensure the detection area matches your ceiling height and room size (OPS305: 3m radius, 100° angle).
-
Communication Protocol: Verify ZigBee 3.0 compatibility for stable mesh networking.
-
Power & Mounting: Micro-USB 5V supply with easy ceiling mounting.
-
OEM/ODM Options: OWON supports customization for system integrators and large-scale deployments.
FAQ
Q1: How is presence detection different from motion detection?
Presence detection senses the existence of a person even when they are stationary, while motion detection responds only to movement. OPS305 uses radar to detect both accurately.
Q2: What is the detection range and mounting height?
OPS305 supports a maximum detection radius of around 3 meters and is suitable for ceilings up to 3 meters high.
Q3: Can it integrate with my existing ZigBee gateway or BMS?
Yes. OPS305 supports ZigBee 3.0 and can easily connect with standard ZigBee gateways and building management platforms.
Q4: What environment conditions can it operate in?
It works from -20°C to +55°C, with humidity up to 90% RH (non-condensing).
Q5: Is OEM or ODM customization available?
Yes. OWON provides OEM/ODM service for integrators and distributors who need custom features or branding.
Conclusion
OPS305 is a professional ZigBee ceiling-mount radar presence sensor designed for smart buildings and energy-efficient automation. It delivers reliable occupancy data, seamless ZigBee 3.0 integration, and easy installation — making it the right choice for system integrators, BMS operators, and OEM partners.
