Xiaomi has released a smart air conditioner that SEES people in the room the Mijia Air Conditioner Human'Sensing Wind 1.5HP.
Its main feature: built-in millimeter-wave radars that detect where people are located. The system analyzes the person's position and automatically adjusts the airflow: it can direct the cold airflow away, gently cool the area nearby, or, conversely, direct the cooling to where you're sitting. If no one is in the room, the air conditioner automatically switches to energy-saving mode.
At the same time, the device is quite quiet (about 16 dB), quickly cools the room in a few minutes, and can "disperse" air up to a distance of 10 meters. All control is via the Mi Home app or the XiaoAI voice assistant.
