has a detection demand for personnel of the Internet of Things. PIR infrared sensors are cheap, but the disadvantage is that they cannot detect static personnel. When the people in the room move weakly or are still, they will cause detection errors.
mm wave radar intelligent human presence sensor has well solved the problems and disadvantages of existing traditional perception technologies such as PIR infrared sensors, single-point ranging laser sensors, etc.
Intelligent service object is people, so whether one can truly achieve "wisdom" is the precise perception of the personnel.
Technology changes life and to create a smart home, the essential thing is the human body existence sensor, which can link the smart devices in the home.
For example, when sleeping in the bathroom in the middle of the night, when the human body moves, it will automatically turn on the night lights when it is detected, no longer use the dark to find the switch, the lights when people walk in the room, etc., all can be achieved through the radar human sensor setting intelligent scenes.
Feirui intelligent human radar sensor has high detection accuracy, and people who are stationary, micro-move or moving can achieve accurate detection; there is no privacy-sensitive problem, no lens design; the detection distance is long, and the detection range can be set freely.
radar Its planar antenna emits extremely low power electromagnetic waves and receives reflected echoes. It has strong anti-interference ability, is less affected by external natural factors, and has stable and reliable performance.
can effectively suppress the interference of high-order harmonic and other clutters, with high sensitivity, strong reliability, safety and convenience. It is a new and practical equipment auxiliary energy-saving product.
electromagnetic waves and filter, mix, amplify, judge and control the received echo signal, output high and low level signals, and control the light and extinguish state of the lamp.
radar sensing can be free from the influence of the environment, temperature, dust, etc. in a normal working environment. These advantages are incomparable to infrared technology sensing.
The main function of the human body existence sensor is to be used as the induction switch , and to set the switch of the smart home by detecting the human body. For example, when combined with lights, the lights can be turned on when people come and turn off when people leave.
Human presence sensor allows smart homes to conduct human-computer interaction more actively. The human presence sensor uses millimeter-wave radar technology to detect tiny movements of the human body.
Feirui intelligent human presence radar sensor can realize the detection of the human body's static existence, light recognition, high sensitivity to sense the movement of the human body and the changes in the light and dark environment, and realize linkage with smart devices at home.
Even subtle movements that are difficult to detect, such as sitting quietly and flirting with books and playing with mobile phones, can be accurately detected and easily identified the existence of the human body. At the same time, it can connect smart homes to complete more meticulous operations.
For example, by sensing the existence of the human body, automatically turning on the air conditioner, adjusting the temperature, or more accurately following the smart light, etc., it truly realizes the effect of "the light is on when the person is on, the light is off when the person is on when the person is on.
