Radar human body microwave sensor detects human body induction to improve the real experience

Radar human body microwave sensor detects human body sensing to improve the real experience. In recent years, the application of human body detection technology in the civilian field is almost blank. Whether it is infrared sensing or radar sensing, human motion is required to detect human presence sensing. Innovative radar The human body microwave sensor can effectively enhance the real experience. In practical applications, such as reading for a long time, meditating, playing with mobile phones and other applications, some sensors will misjudge that no one exists, and then execute the command to turn off the lights, resulting in poor user experience. Therefore, the user's satisfaction with the human body sensing application experience is not enough. Many manufacturers go through a journey from getting started to abandoning the standard when choosing a human presence sensing solution.

Human presence sensing radar technology adds breath sensing detection function to the human body sensing field, helping users achieve success in experience. Using patented cross-polarized and high isolation flat panel dual antennas. This antenna has extremely high sensitivity, can detect the ups and downs of the chest and abdomen and other small movements, and is used for human breathing, and has a simple process and good consistency. Using advanced software algorithm, the weak waveform of chest ups and downs is effectively extracted from various complex waveforms, so as to effectively judge whether someone is within the detection range. This algorithm not only extracts valid breathing signals, but also masks other disturbances, such as exhaust fan rotation, movement of people slightly further away, rotating machines, etc.

The radar body microwave sensor uses system integrated chip technology and has high consistency. When it senses someone entering the office, the sensor can accurately identify and turn on other devices such as lights and air conditioners, enabling true intelligence to detect large movements, people's breathing when they sit or move slightly.

The radar human body microwave sensor is applied in the hotel room. After the person enters, the radar sensor is triggered, and the indoor light is automatically turned on when the person is detected, so as to realize the power-free access. The principle of human microwave radar sensor is to use ultra-wideband for high-precision micro-motion detection, which can detect human breathing, moving objects, static or sleeping people, and it can be installed through the ceiling. The sensing sensitivity of the radar sensor is higher than that of the human body's infrared sensing. The sensing distance is about 12-20 meters. The sensing object has obvious movement and is not affected by factors such as ambient temperature.
