The Aqara Presence Sensor FP1E uses mmWave radar technology to detect people in a room, ensuring that lights or appliances stay on even when you are sitting perfectly still. This is made possible by the TriD-Space AI, which helps the sensor ignore interference from pets, mirrors, glass, or electrical devices that might otherwise trigger false alerts. Designed for versatility, the white device measures 57 x 50 x 37 mm and features a rotating sensor head that allows you to aim the detection area precisely. It covers a distance of up to 6 meters with a 120° viewing angle, making it easy to monitor most standard rooms from a wall, ceiling, or corner installation using the included magnetic mount or sticker. Because it is powered via a USB connection (5V / 1A), you won't have to worry about replacing batteries. To integrate this sensor with ecosystems like Alexa or Google Home, you will need an Aqara Zigbee hub, allowing you to create automated environments that respond to your actual presence.
