It combines three sensing technologies, offers long battery life, flexible installation and quick automation without the need for a hub in simpler scenarios. This makes it ideal for places where standard sensors are not enough – in the bathroom, home office, living room or reading corner – anywhere you might be idle for extended periods of time. It is a sophisticated solution for those who want greater comfort, better control over lighting and appliances, and privacy without cloud storage or recording. \u003c\/p\u003e\u003cp\u003e\u003cimg alt=\"Presence sensor mounted on a white wall next to a wooden door frame.\" src=\"https:\/\/assets.innpro.pl\/20915\/27770\/1.jpg\"\u003e\u003c\/p\u003e\u003ch3\u003e Three technologies in one device\u003c\/h3\u003e\u003cp\u003e Unlike standard motion sensors, SwitchBot uses an advanced 3-in-1 system that combines a light sensor to detect ambient light levels, a PIR sensor to detect motion quickly, and a mmWave radar to detect presence. This combination significantly increases speed and accuracy, as the device is not limited to detecting motion alone, but can also recognize the presence of a person standing still. The sensor even detects the movement of a stationary person's chest, making it ideal for use while bathing, working at a desk, resting, or reading. In practice, this means no more situations where the light turns off simply because you haven't moved for a moment. \u003c\/p\u003e\u003cp\u003e\u003cimg alt=\"A small presence sensor mounted on the wall in a minimalist bathroom above a cabinet.\" src=\"https:\/\/assets.innpro.pl\/20915\/27770\/7.jpg\"\u003e\u003c\/p\u003e\u003ch3\u003e No more unwanted light switches off\u003c\/h3\u003e\u003cp\u003e One of the biggest advantages of the SwitchBot occupancy sensor is its ability to distinguish between normal movement and the presence of a person in a room. This is especially important in rooms where you often linger without much movement, such as the bathroom, home office, bedroom or living room. Thanks to mmWave technology supported by PIR and a light sensor, the system can keep lights on or activate specific devices exactly when needed. Instead of annoying interruptions and unintentional switching off of lights, you get a more natural, convenient and smart control of the entire room. \u003c\/p\u003e\u003cp\u003e\u003cimg alt=\"A presence sensor on the wall directs a signal towards a woman reading a book on the couch.\" src=\"https:\/\/assets.innpro.pl\/20915\/27770\/4.jpg\"\u003e\u003c\/p\u003e\u003ch3\u003e Wide range and more complete coverage of the space\u003c\/h3\u003e\u003cp\u003e SwitchBot offers a wide 120° detection angle, allowing you to cover a larger area without the need for complex installation planning.
