Radar Sensing
for Smart Living
Smart spaces should respond to people, not just to motion. mmWave radar knows when someone is there, how many people are in a room and how a hand is moving — all without a camera.
Presence Detection
The lights switch off while you're reading, and the air conditioning keeps running in an empty room.
Motion (PIR) sensors only notice large movements, so a person sitting still looks like an empty room. Radar picks up the small movements of breathing, keeping lighting and climate on while people are there and off once they leave.
- Detects people even when they sit still
- Cuts energy spent on empty rooms
- Hides behind panels and fixtures
People Counting
Facility managers need to know how meeting rooms, offices and stores are really used, but cameras raise privacy concerns.
Radar counts how many people are in a space and where they move, without recording faces or identities. The result is reliable occupancy data for planning space, staffing and energy use.
- Real-time occupancy counts
- Anonymous by design
- Data for space and energy planning
Gesture Control
In the kitchen or bathroom, wet or messy hands and touch panels don't mix — and voice commands don't suit every room or every moment.
Radar recognises hand gestures in the air — a swipe, a tap, a turn — even behind a cover or panel. Because the sensor can sit hidden inside the product, appliances, lighting and displays can be controlled without a touch.
- Touch-free control
- Works behind covers and panels
- No visible sensor on the product
Home Security
People want to know their home is safe while they're away, but not with cameras in the living room.
Radar detects a person moving inside the home and is less easily fooled by drafts or temperature changes than PIR sensors. No video is recorded, so privacy stays at home.
- Mounts out of sight, behind panels
- Fewer false alarms than PIR sensors
- No video recorded
Illustrative scenario. Actual performance depends on sensor configuration, installation and system integration.
Every presence sensor has a role.
Radar adds what the others can't.
Motion sensors miss people who sit still, and cameras watch. Radar knows when someone is there and how many, without capturing images.
