Battery-powered Zigbee presence sensor with 24 GHz mmWave radar, adjustable sensitivity, and privacy-friendly occupancy detection for smart home automations.

Zigbee 3.0 24 GHz mmWave Battery powered

Product Description

Upgrade your smart home with a compact 24 GHz mmWave radar presence sensor that detects human presence and subtle motion without using a camera. It is designed for flexible placement in spaces such as hallways, bathrooms, cabinets, storage rooms, and other areas where wired power is inconvenient.

  • Advanced mmWave detection: Detects presence through common non-metallic materials such as wood and glass, and remains stable across changes in light, temperature, and humidity.
  • Battery powered placement: Powered by three standard AA batteries, so it can be installed without wiring or a nearby outlet.
  • Zigbee 3.0 connection: Requires a compatible Zigbee hub or coordinator. Supports platforms such as Home Assistant (ZHA or Zigbee2MQTT), SmartThings, Aeotec, Homey, Hubitat, and Echo devices with built-in Zigbee hubs.
  • AI-enhanced stable detection: Environment learning helps reduce false triggers from everyday background movement, such as airflow or slight curtain movement. Strong or repetitive motion, such as fans, may still trigger detection.
  • Adjustable sensitivity: Five sensitivity levels help tune detection for different rooms. Use higher sensitivity for subtle movement and lower sensitivity in hallways or pass-through areas.
  • Automation ready: Use presence or absence as a trigger for lights, thermostats, curtains, security cameras, and mobile alerts in compatible smart home systems.

Leo Y. ★★★★★

The mmWave radar is impressively fast at catching motion even when someone’s sitting still in a chair, which is exactly what I needed for my lighting automations. Battery life seems solid so far, and the privacy-friendly detection is a nice peace of mind. Glad I switched from a basic motion sensor.

Chloe R. ★★★★★

Setup took me about ten minutes and it paired with my Zigbee network without any drama. The adjustable sensitivity is a lifesaver since my cat used to set off my old motion detector constantly, but now the radar only triggers when I'm actually in the room.

Emma ★★★★★

The 24 GHz mmWave radar catches me moving even when I’m sitting perfectly still, which my old motion sensor never did. Sensitivity adjustment took a minute to dial in, but now it triggers my lights exactly when I want, no more false offs.
