What Is a Zigbee Radar Occupancy Sensor?
Traditional PIR motion sensors often fail to detect occupants who remain still, leading to inefficient HVAC operation and unnecessary energy consumption in smart buildings. A radar-based zigbee occupancy sensor solves this problem by enabling accurate, real-time human presence detection.This type of zigbee presence sensor is increasingly used in smart building automation where accurate occupancy detection is required.
The OPS305 zigbee occupancy sensor uses advanced radar technology to identify micro-movements such as breathing or slight posture changes, ensuring reliable detection even when occupants are stationary.As a built in radar occupancy sensor, it provides significantly higher accuracy than traditional PIR-based motion sensors.
With improved accuracy and reduced false triggers, radar-based occupancy sensing is a critical upgrade for modern building automation projects.
Main Features:
• ZigBee 3.0
• Discern presence, even if you are in a stationary posture
• More sensitive and accurate than PIR detection
• Extend the range and strengthen ZigBee network communication
• Suitable for both residential and commercial application
Application Scenarios:
The OPS305 is widely deployed in scenarios where motion detection alone is insufficient:
• HVAC occupancy-based control
Maintain heating or cooling only when spaces are truly occupied
• Office and meeting rooms
Prevent systems from shutting down during long, low-movement meetings
• Hotels and serviced apartments
Improve guest comfort while reducing energy consumption
• Healthcare and elderly care facilities
Detect presence without requiring active movement
• Smart building automation systems (BMS)
Enable accurate space utilization and automation logic
Frequently Asked Questions
Q: Can the OPS305 replace traditional motion sensors?
In many professional applications, yes. Radar occupancy sensors provide more accurate presence detection, especially in environments where occupants remain still for extended periods.
Q: Is radar-based sensing safe?
Yes. The OPS305 operates at extremely low power levels and complies with applicable safety standards for indoor sensing devices.
Q: Can multiple OPS305 sensors be used in one project?
Yes. Large projects often deploy multiple sensors across zones, all connected through the Zigbee mesh network.
Q: Does OPS305 support Home Assistant or Zigbee2MQTT?
A: Yes. Based on ZigBee 3.0, OPS305 can be integrated with Home Assistant or Zigbee2MQTT via compatible Zigbee gateways or coordinators.
