SwitchBot W1101500 Smart mmWave Radar Motion Sensor with Dynamic Detection & Zone Positioning: Motion & presence detection with mmWave radar, light-sensing, and PIR sensor for accurate human detection
For the parent working from a home office or the professional needing uninterrupted focus, this sensor solves a common frustration: lights turning off while you're still in the room. It detects subtle movements like breathing, so your bathroom light stays on during a long soak or your study lamp remains lit while you read.
Unlike basic motion sensors, its mmWave radar provides presence detection that feels intuitive. You'll notice it keeps lights on during a video call without a false trigger from a ceiling fan. Pair it with a SwitchBot Hub for automations, like turning on an air purifier when you enter your home office, enhancing your daily routine without manual input.
With a 2-year battery life and magnetic base, installation is simple in any room. It works with Alexa and Apple Home for voice control, making it a seamless addition to your smart home setup.
