Microwave radar induction module technology, real-time intelligent detection of human existence, static micro motion and static perception

Radar human body sensing technology can detect the presence of stationary people in real time , combination FMCW High precision and low power consumption of pulse radar ; The module adopts serial port UART Output , Permeable ceramics 、 Plastic shell 、 Glass and other panels , Beautiful and generous .

Different from the traditional human body infrared induction module , The radar human body sensing module can detect the presence of a stationary human body , And most environmental interference can be avoided by accurately setting the sensing distance .

Intelligent radar human body has induction module , Can achieve 3 Micro motion detection of human body within meters 、 Static human body detection and other functions .

The radar sensing module is an active sensor , The sensor emits high-frequency electromagnetic waves and receives their echoes , This sensor detects changes in the echo , Even small movements within the detection range , Then trigger the command .

Microwave radar induction module is based on the principle of Doppler radar , It can effectively suppress the interference of high-order harmonics and other clutter 、 High sensitivity 、 High reliability 、 Safe and convenient 、 Intelligent energy saving , It is a new and practical energy-saving product .

If the reflection frequency of the sensing area is detected to change , The sensor triggers the action , The output signal turns the load on or off as needed . It is suitable for induction lamps and security alarm devices , Like corridor 、 corridor 、 The garage 、 balcony 、 yard 、 Garage induction lamp , And as an energy-saving switch or anti-theft alarm device .

Intelligent radar module , Adopt advanced planar technology antenna to transmit and receive microwave . Use active sensors , The sensor emits high-frequency electromagnetic waves and receives echoes . Strong anti-interference ： Little affected by external natural factors , Stable and reliable performance .

use 3.3V Voltage supply , A serial port communication , It can be connected to the main control board through serial port communication as a controlled module , It can also be used alone , At present, it is widely used in intelligent lighting 、 Smart home 、 Smart bathroom 、 Smart appliances and other fields .

The radar sensing module realizes that the light is on 、 When people walk, the lights go out , Safety and power saving , Silence 、 Interference from external factors such as environment . Onboard integrated IF demodulation , Signal amplification , Digital processing , Light intensity detection , Timing and other functions on the module .

There is an inductive radar module in the human body , Micro motion sensing 、 Small anti-interference volume 、 High sensitivity 、 High stability 、 Good consistency 、 It has the characteristics of good clutter and high-order harmonic suppression effect .

It can realize tiny motion sensing in a small range , As well as breathing, a slight human vital sign . Not limited by light and privacy , Determine whether there is someone by measuring physiological respiration .

The economy of radar products is high , The signal output is simple , Facilitate scene interaction , Because of its penetrability , It is very convenient to install the radar into household appliances and lamps to form a complementary linkage .
