The Meross Intelligent Presence Sensor is an advanced device that combines advanced presence and motion detection technologies. Equipped with an innovative dual detection technology that combines millimetre wave Doppler radar technology and infrared motion sensors, this sensor enables precise detection of biological movements as well as subtle movements. The sensor is able to not only register movement, but also recognise the presence of a person, even if they are not moving. This reduces false alarms and improves the reliability of the system. In addition, the sensor has an integrated brightness sensor that detects changes in ambient brightness in real time. This information is quickly transmitted to the Meross system or the Matter platform, enabling seamless integration into a smart home system. The Meross presence sensor can support various automation scenarios, such as automatically switching lights on and off to create a more comfortable living experience.
