Radio wave sensor, radio wave sensor system, illumination device with radio wave sensor, and method of controlling radio wave sensor in radio wave sensor system

摘要

A radio wave sensor, a radio wave sensor system, an illumination device with a radio wave sensor, and a radio wave sensor in a radio wave sensor system, in which a mobile body outside a desired area is difficult to detect and a mobile body inside a desired area is easily detected. Provide a control method. A Doppler sensor detects the presence or absence of a moving body based on reception of a reflected wave of a transmitted radio wave. (EN) A Doppler sensor capable of taking a high state in which the performance of detecting the presence or absence of a moving body is high and a low state in which the performance thereof is lower than the high state. The Doppler sensor waits in the low state when the state in which the moving body cannot be detected continues for the first predetermined time. [Selection diagram] Fig. 7
