SwitchBot Motion Sensor is designed for users who expect more from a smart home than simple motion detection. It combines three sensing technologies, offers long battery life, flexible installation options, and supports fast automations without requiring a hub for basic scenarios. It is ideal for bathrooms, home offices, living rooms, bedrooms, or reading corners—anywhere a person may remain still for an extended period. This advanced solution delivers greater comfort, smarter automation, and enhanced privacy without cloud storage or recording.
Three Detection Technologies in One Device
Unlike traditional motion sensors, the SwitchBot Presence Sensor uses an advanced 3-in-1 detection system that combines an ambient light sensor, a PIR motion sensor, and mmWave radar technology. This combination provides exceptional speed and accuracy, allowing the device to detect not only movement but also the presence of a stationary person.
The sensor can even detect subtle chest movements caused by breathing, making it perfect for bathrooms, home offices, bedrooms, or relaxation areas. As a result, lights and other connected devices remain active even when you are not moving.
No More Unwanted Light Shut-Offs
One of the biggest advantages of the SwitchBot Presence Sensor is its ability to distinguish between motion and actual human presence. This is especially useful in spaces where people often remain still, such as bathrooms, home offices, bedrooms, or living rooms.
Thanks to mmWave technology combined with PIR and ambient light sensing, the system keeps lights and connected devices running precisely when needed. The result is a more natural, comfortable, and intelligent automation experience without frustrating light shut-offs.
Wide Coverage Area
The sensor offers a detection angle of up to 120°, allowing larger areas to be monitored without complicated installation planning.
- Detection range for moving people: up to 8 meters
- Detection range for stationary people: up to 5 meters
These capabilities make the sensor effective in both small rooms and larger open spaces. Whether controlling entrance lighting, enhancing remote work comfort, or automating daily routines, it delivers reliable and accurate performance.
Long Battery Life and Installation Freedom
The wireless design allows the sensor to be placed exactly where it is most effective, without the limitations of power cables. It can be installed on desks, bookshelves, or metal surfaces using its magnetic mount.
With an IP55 rating, the device is suitable for use even in humid environments such as bathrooms.
The low-power mmWave radar enables up to 2 years of operation on a single set of batteries, providing outstanding convenience and flexibility.
Magnetic Base and Flexible Installation
The magnetic base offers maximum installation flexibility. The sensor can be wall-mounted, placed on flat surfaces, or adjusted to optimize the detection angle for a specific room.
This flexibility helps improve coverage, reduce false triggers, and maximize automation performance.
Fast Automations Without a Hub
The sensor supports direct interaction with compatible SwitchBot devices without requiring a central hub. This ensures near-instant response times and allows simple local automation scenarios.
Up to two local automations can be configured directly, which is sufficient for many everyday applications. For more advanced multi-device automations, the sensor can be connected to a SwitchBot Hub.
Reduced False Alarms
The built-in AI self-learning feature automatically filters out interference caused by fans, air conditioners, and other movement sources unrelated to human presence.
Combined with adjustable detection zones and flexible positioning, the sensor can also minimize false triggers caused by pets and other environmental factors.
