Innovative Sensors for a Breakthrough Home Experience! Xiaomi has demonstrated the perceptual position of sensors in the smart home
Sensors play a very important role in the intelligent era and are the source of all perceptions, especially in smart homes.
The perception ability of smart home devices comes from sensors and sensor chips, and the breakthrough of sensor technology and function is a crucial factor in the function, performance and experience improvement of smart home, and it is also a major difficulty in development and design.
The highlight of the Xiaomi sensor is that it only needs a CR2450 coin cell battery, which lasts up to 3 years, and can be installed anywhere in the home without the shackles of wires. This is thanks to the sensor's ultra-low-power millimeter-wave radar, which captures breathing, chest bulges, and other small movements as small as 0.5GHz.
In addition to ultra-low-power millimeter-wave radar, it is also equipped with illuminance sensors and pyroelectric sensors, through the deep fusion algorithm of the three sensors, Xiaomi people support 130 ° wide-angle perception in the sensor, which can be easily covered from the bathroom to the living room, meeting all kinds of space needs, and can dynamically perceive the human body within 6 meters (static perception within 4 meters), known as "people are always on the lamp, even if they don't move, they can accurately perceive".
What is the use of human sensors? Xiaomi showed everyone the importance of sensors as a source of home perception and the pull on downstream applications.
In the article that introduces why people choose Xiaomi for sensors, Xiaomi takes people in sensors as the core device of home perception, and through people in sensors, fans, air conditioners, purifiers and many other Mijia smart homes can be controlled, and technology can truly bring a better life.
