Abstract: At present, environmental sensing sensors widely used in air conditioners are mainly infrared sensors and cameras. Such optical devices cannot effectively protect privacy, which makes users have a repulsive mentality. And the cameras are greatly affected by light and cannot work around the clock. So they are not the best choice of environmental sensing sensors. Unlike these sensors, millimeter wave benefitting from the physical characteristics of electromagnetic wave, which can achieve high-precision distance, angle, speed measurement, as well as target identification and tracking, can almost work in the dark, strong light, haze, rain and snow and other bad weather without problem of privacy leakage, it is a very suitable choice of environmental sensor. The application of 60 GHz millimeter-wave radar on air conditioner proves its high data reliability and can be further studied.
