SwitchBot has introduced a new, battery-operated presence sensor that boasts superior accuracy compared to conventional motion detectors and can operate for up to two years on just two AAA batteries.
This device could be the solution for those who have experienced frustration with lights turning off while they remain stationary.
The innovative sensor combines a 60Hz mmWave radar, a traditional PIR sensor, and an integrated light sensor. This combination provides a level of sensitivity that most budget sensors lack. The PIR sensor triggers quickly when someone enters a room, while the mmWave radar detects minor movements, such as slight changes in posture or even breathing. This ensures that the room remains "occupied" even if the person is not moving, addressing a common issue with PIR-only devices.
SwitchBot has also incorporated intelligent features. The sensor uses AI-based environmental learning to identify and filter out interference from sources like fans or air conditioners. Additionally, a pet-avoidance function helps minimize false triggers caused by small animals. By integrating data from motion, micro-motion, and ambient light, the sensor can provide genuinely context-aware automation, ensuring that lights and appliances are only activated when necessary.
Thanks to its battery-powered design, the sensor offers versatile installation options. It can be attached to walls, furniture, or metal surfaces using its rotatable magnetic base. With an IPX5 rating, it is suitable for use in bathrooms as well. The sensor's range is impressive, with up to 8 meters for movement detection and 5 meters for static presence, making it ideal for small to medium-sized rooms.
The sensor supports a wide range of smart home systems. It is compatible with Matter through a SwitchBot Matter-enabled hub, Home Assistant, and major voice assistants. Importantly, it also supports local automation, ensuring that routines continue to function even without an internet connection.
The SwitchBot Presence Sensor is now available on the SwitchBot website, priced at $29.99 / £32.99 / €32.99, offering exceptional value for a device with such advanced capabilities.
