Our take on the 4X Tuya WiFi MmWave Human Presence Sensor with Luminance MicroWave Radar Detection PIR Motion Sensor Wall Mount

A four-pack of wall-mount Tuya sensors that combine mmWave radar with PIR motion detection and a luminance sensor. The mmWave radar picks up small movements like breathing or typing, so lights and automations stay on while someone is in the room instead of switching off when they sit still. It works over 2.4 GHz WiFi with the Tuya Smart or Smart Life app and pairs with Alexa and Google Home. No price was given for this listing, so compare the four-pack cost per sensor against single-sensor listings before buying.

Best forSmart-home users who want lights to stay on while sitting still
Home offices and living rooms with occupancy-based automations
Anyone replacing a plain PIR sensor that switches off too soon
Buyers wiring several rooms at once with a four-pack

Questions and answers

How is this different from a normal PIR motion sensor?
PIR only reacts to moving heat, so lights can turn off when you sit still. The mmWave radar here detects small movements like breathing or typing, so presence stays detected while you are in the room.
Does it need a hub or neutral wire?
No hub is needed. It connects directly over 2.4 GHz WiFi to the Tuya Smart or Smart Life app. It does need a power source at the mounting spot.
Will it work with Alexa and Google Home?
Yes. Tuya devices link to Alexa and Google Home through the app, so you can use presence to trigger routines and voice scenes.
Can I adjust the range and sensitivity?
Yes. Detection range and sensitivity are adjustable in the app, up to about 9.5 m. Lower the sensitivity if it triggers through walls or doors.
Is the four-pack worth it over buying singles?
It depends on the per-sensor price, which was not listed here. Compare the four-pack total against single-sensor prices; the pack makes sense if you are covering several rooms.
What is in the box?
Four white wall-mount sensors. Mounting hardware and a power adapter are not confirmed in the listing, so check before ordering.
Where can I buy the 4X Tuya WiFi MmWave Human Presence Sensor with Luminance MicroWave Radar Detection PIR Motion Sensor Wall Mount?
