This is a Zigbee 3.0 human presence sensor that uses 5.8 GHz mmWave radar to detect both motion and stationary presence, unlike passive infrared sensors that miss people who are still. It also includes a 0–500 lux illuminance sensor and a configurable departure delay, so it can trigger lights only when the room is dark and keep them on after someone leaves. It suits smart-home users who want reliable occupancy automation for lighting or HVAC, but it needs a Zigbee hub and is not a standalone device. Compared with PIR sensors, it offers presence detection and lux sensing, but it is more complex to set up and tune.

This is a millimeter-wave radar human presence sensor with a built-in illuminance sensor. It connects over ZigBee 3.0 and runs on 85-265 VAC input.
It detects people across a 120 x 120 degree beam at 5.8 GHz. The sensing distance is 0-11 m, with a default of 6 m. Presence is detected within a radius of up to 2.5 m, and motion within 4-5.5 m. Sensitivity is adjustable from 1 to 9, with a default of 7.
The departure delay can be set from 0.5 seconds to 25 minutes. Setting it to no less than 15 seconds is recommended, as shorter delays may cause missed detection. The built-in relay can switch resistive loads up to 3000 W and LED loads up to 300 W.
