Ultra-wideband communication (UWB) is a radio technology that uses a broadband frequency, and has various advantages such as high distance resolution, transparency, strong immunity to narrowband noise, and coexistence with other devices that share a frequency. For example, ultra-wideband communication (UWB) has an advantage in that even a minute movement of an object can be detected in an ultra-precise distance resolution characteristic of 1 cm or less. The UWB radar system generates an impulse signal having a time width of several nano-several picoseconds in the signal generator and radiates it at a wide angle or a narrow band angle through a transmission antenna. The radiated signal is reflected by various objects or people in the environment, and the reflected signal may be converted into a digital signal through a receiving antenna and an analog-to-digital converter (ADC).

The sensor unit 110 includes an electromagnetic wave generator 111 that is installed on the inner wall surface of the residential space 16 to irradiate electromagnetic waves into the residential space 16, and receives the electromagnetic waves reflected in the residential space.
