Occupancy Sensor is an intelligent home device used to detect the occupancy of a room. It uses technologies such as infrared or ultrasonic waves to detect changes in motion, heat and sound in the surrounding environment and identify whether there are people inside the room based on these changes. Once someone enters the room, the Occupancy Sensor will automatically turn on lighting, adjust temperature and humidity levels, etc., to improve the user’s comfort and convenience. When there is no one in the room, the sensor will automatically turn off lighting and other electrical appliances, saving energy and reducing maintenance costs. Occupancy Sensor can be paired with smart home systems to enable a smarter and more convenient lifestyle.
