Presence Sensor
A presence sensor detects both motion and stillness using radar or mmWave, so it knows you are in a room even when you are not moving. Often supports configurable zones.
Presence sensors solve the most common problem with traditional motion sensors: a stationary person being treated as absent and triggering “lights off while I am still here.” The trade-off is that radar and mmWave hardware costs more, draws more power, and is rarely battery friendly.
Many presence sensors also support configurable detection zones, so a single sensor can distinguish between the couch, the desk, and the doorway in the same room.
How Selora AI uses presence sensors
- Reliable room occupancy for lighting, climate, and entertainment automations.
- Zone-aware recipes that respond differently depending on which part of a room is occupied.
- Severe weather and security recipes that wake or alert only the occupied rooms.
- Energy savings by precisely matching HVAC and lighting to where people actually are.
