Millimeter wave radar human sensor, as a kind of high precision and high stability human presence sensor, is gradually favored by the market. This paper will deeply analyze the working principle of millimeter wave radar human sensor, the characteristics of sensing area and its application in various fields, so as to provide readers with a comprehensive and in-depth understanding.

First, the working principle of millimeter wave radar human body sensor

Millimeter wave radar body sensor mainly uses millimeter wave signal to detect human body. Millimeter wave refers to the electromagnetic wave with a wavelength between 1 and 10 mm, which has the characteristics of strong penetration, good anti-interference and high resolution. Millimeter wave radar can detect the presence of human body by transmitting millimeter wave signal and receiving the signal reflected back by human body.

When the body sensor is working, it constantly emits millimeter wave signals and scans the surrounding environment. When a human body enters the sensing area, the human body will reflect the millimeter wave signal. After receiving the reflected signal, the sensor will determine the presence of the human body through signal processing and analysis, and output the corresponding signal.
