radar sensing uses the Doppler effect principle design to detect the existence of an object in a non-contact manner, thereby generating corresponding switching operations.
radar human presence sensor automatically realizes the effect of the lights coming on and off. It is often used in indoor environments such as corridors and corridors, such as frequent flow of people.
radar sensing has good radio frequency interference capabilities, is not affected by temperature, humidity, light, air, dust, etc., and its detection function is stable. Compared with using infrared to sense the presence of the human body through temperature, the radar sensor has the advantages of being significantly low incorrect triggering (can be filtered through algorithms), large sensing area (configurable antennas), and accurate and effective triggering (feature points can be reused).
Feirui intelligent human respiratory presence sensor has solved the current pain points in the industry and achieved static human monitoring.
feature extraction through the distance, phase, breathing, heartbeat and other electromagnetic wave feedback signal data after the human body enters the environment, and then analyzes whether the human body exists in the environment.
can not only perceive dynamic human body, but also accurately perceive static signs. In the scene of hanging 3 meters high, it can effectively detect the breathing of the human body in the 40 square meters environment, and the large movements of more than 100 square meters.
radar sensing not only has high detection sensitivity, but also has a wide detection range. Moreover, it works reliably, and is incomparable to the circuits composed of infrared , ultrasonic , and pyroelectric components in the past.
radar sensing is equipped with high gain antenna , and is also equipped with a remote control design, which can adjust parameters and is easier to install.
In order to better meet customers' customized needs in diverse scenarios, the sensitivity, delay and distance of the device can be adjusted through APP or dialing, thus greatly improving the product's adaptability to the environment.
People or objects reach their sensing range, and the frequency of radar sensing will change and output signals. If a person or object is always within its range, it will continue to output and receive signals.
When someone enters the detection range of radar sensing switch , the radar sensor lights up. When the person leaves the detection range, the light automatically goes out, and intelligently sets the delay application.
Feirui intelligent radar human presence sensor provides a variety of interfaces including dry contact , Qiang Power, PLCh, 485, and the communication method can also support various mainstream communication methods such as Tuya/Private Cloud/LORA/NB.
fully supports the mainstream communication protocol , achieving the effect of device linkage, and is widely used in hotels, apartments, office environments, smart homes and other places, truly achieving energy-saving and intelligent.
When a person enters the office, he passes the human presence detection and turns on the light, and the person detects his breathing when he sits down or moves slightly, and determines whether the person leaves, so as to accurately execute whether the lights are turned on and air conditioners, etc., to achieve true intelligence.
