The sleep meter can create a magnetic field that simulates the earth's energy by releasing Schumann waves, helping to create a deep sleep environment, extending deep sleep time, and creating high-quality sleep quality. At the same time, in addition to the physical switch, it also has a voice control function. Through voice control, sound waves such as light music/white noise are played to promote the human body to sleep quickly. The design form is biased towards the round and minimalist Nordic home style, which gives people a close and comfortable feeling visually and is easier to integrate into the home environment.
