Xiaomi has unveiled a new smart motion sensor that can pick up movements as small as a wave, and can run for three years before its battery needs replacing. The Motion Sensor 2S is a successor to the original Xiaomi Motion Sensor released in 2019, and offers some big improvements in sensitivity, power efficiency, and responsiveness.
The new sensor (which can be used freestanding or mounted on a wall or ceiling using an adhesive pad) can detect motion from up to seven meters away, and has a three-meter 'high sensitivity detection' range, at which it can pick up movements as small as hand gestures.
