Zigbee mmWave Sensor (USB)

The Zigbee mmWave Sensor with USB power uses 24 GHz radar to detect human presence — not just movement, but the micro-motions of someone sitting still. Where a PIR sensor goes blind the moment you stop moving, this sensor continues to register your presence through the subtle shifts of breathing and heartbeat. Lights and climate stay on because the room genuinely knows you are there. The practical difference is felt daily. You are reading at a desk and the lights do not turn off after five minutes of stillness. You are watching television without fidgeting and the room remains comfortable. You step into a meditation space and the environment holds steady for as long as you remain. The integrated LUX sensor adds brightness awareness, enabling automations that consider both presence and ambient light level before acting. Powered by any 5V USB source, it mounts flexibly on walls, ceilings, or surfaces — wherever provides the best coverage angle for the room geometry. It communicates over Zigbee 3.0, joining your existing mesh network. The USB form factor makes it easy to reposition and experiment with placement during setup. For rooms where occupants are often stationary — home offices, living rooms, bedrooms — this sensor eliminates the single most common frustration with motion-based lighting automation.
