Abstract
- 24GHz radar presence detection: Detects steady occupancy — not simply movement — so the unit will not swap off if you happen to stand nonetheless within the bathe. Adjustable vary and sensitivity stop false triggers from folks strolling previous the door.
- 3,000W graphene heating ingredient: Variable frequency management maintains a set temperature with out operating at full energy continually. An oscillating louver swings 60–90 levels to push heat air towards the ground.
- Twin DC motors: Permits heating and exhaust air flow to run concurrently. Exhaust rated at 259 cubic meters per hour.
- Retractable lighting panel: As much as 1,500 lumens, 3,000K–6,200K colour temperature vary, with an evening mild mode for low-light use.
- 999 yuan (~$148), crowdfunding subsequent week: IPX4-rated wi-fi wall swap included, becoming commonplace 86mm electrical packing containers with no new wiring required.
Why 24GHz Radar Over a Normal PIR Sensor

The sensitivity adjustment is the considerate addition. Radar is extra penetrating than infrared — with out tuning, it may detect somebody strolling previous a closed door. Xiaomi’s adjustable detection vary prevents that.
Heating That Would not Waste Vitality
The three,000W graphene ingredient heats rapidly, however what retains operating prices cheap is the variable frequency management. Quite than biking between full energy and off, the unit throttles output to keep up your goal temperature. The oscillating louver distributes warmth actively — swinging between 60 and 90 levels directs heat air down the place it is wanted slightly than letting it pool on the ceiling.
The Set up Benefit
The included wi-fi wall swap matches a regular 86mm electrical field. Which means you may add a bodily management level with out opening partitions or pulling new wiring — a real-world set up profit that almost all good residence ceiling models ignore. The unit ties into the Mi Dwelling app and HyperOS ecosystem for scheduling, voice instructions, and integration with different Xiaomi good residence gadgets.
