SwitchBot Smart mmWave Radar Motion Sensor, Bluetooth Presence Sensor with Dynamic Detection & Zone Positioning, Compatible with Alexa, HomeKit & Apple Home via SwitchBot Hub, 2-Year Battery Life

Motion & Presence Detection: Presence Sensor combines mmWave radar with light-sensing technology and PIR sensor to accurately detect subtle chest movements from stationary humans. Perfect for bathrooms, reading, or office use, it prevents lights from turning off unexpectedly and enables automated lighting.

Battery Design & Flexible Installation: Equipped with a long-lasting battery, this sensor frees you from power cables and can operate up to 2 years on a single charge. The magnetic base allows flat placement, wall mounting, and adjustable detection angles, making it ideal for bathrooms, living rooms, studies, and other areas throughout your home.

Smart Automations: Presense Sensor works without a hub for instant, second-level response. Seamlessly pair with SwitchBot devices (e.g., Bot, Curtain, Light Series, etc. ) with local linkage and set up to 5 automations. For more complex automations, pair with a SwitchBot Hub to trigger smart scenarios, such as automatically turning on lights and air purifiers while working from home.

AI Anti-Interference: Enable AI self-learning with one click to automatically filter out interference from fans, air conditioners, and more, improving detection accuracy. The magnetic base allows the Presence Sensor to rotate and adjust its detection zone, effectively preventing false triggers from pets and meeting diverse home needs.

Full-Scene Coverage: 120° wide-angle detection with a range of up to 8 m for moving humans and 5 m for stationary humans. Ensures complete coverage from bathroom to living room, meeting the sensing needs of every space.

Multi-Platform Compatibility & Voice Control: Presense Sensor supports Apple Home via SwitchBot Matter Hub, Home Assistant, Alexa, Google Home, and other platforms.
