Millimeter Wave Radar Sensor for Human Persence Detection

Introduction:

The ST-CD101W radar sensor for capturing human pose is based on the millimeter wave Doppler frequency modulation continuous wave radar system, which realizes the static perception of human biological motion and human biological perception. Through the synchronization of the Doppler parameters of the human movement and the synchronization of the human physiological parameters, the state of the personnel in a specific place is realized Wireless perception, through wireless signal notification gateway to achieve scenes linkage; suitable for homes, hotels, offices and other places. (Not affected by factors such as temperature, humidity, noise, airflow, dust, light, etc.)




Detection Range Description:
1. It is recommended that the ceiling installation height is 2.75m away from the ground

2. Detection range
The range when the ceiling installation radar detects human activities is about 6X8m, the range when the human body is stationary is about 4X6m, and the range when scanning sleep is 3.6X2.2m. The radar installation location needs to be designed according to the room structure.

3. Scenario mode function: (data is tentative data, need to wait for test data combination optimization)

Installation:

1. Select the installation location according to the detection range of the product and the room layout to ensure that the room can be effectively covered;
2. The diameter of the product is 86MM, and the recommended hole diameter is about 60MM.

Distribution Network Description:

After the product is powered on, it will automatically turn on. Press and hold the button for 5-10 seconds to configure the network. At this time, the red light is always on. After 5 seconds, release the button and the red light flashes to start the network configuration. If the network distribution is successful, the red light will stay on for 5 seconds. If the network configuration fails, the red light will go out.




Precautions:

1. This product uses radar to scan human breathing to determine the presence of human body;
2. If there is a moving object within the radar range, the radar will sense the existence of the object and judge the existence of life;
3. Personnel enter within 0.5 seconds to report someone; if personnel leave, the radar will have a delay of about 3 minutes output;
4. The radar detection range is related to the electromagnetic field environment around the room, and there may be a small distance error;
5. Radar scanning will penetrate glass, veneer, gypsum board, partition walls and other low-density objects, but cannot penetrate human bodies, liquids, and metal objects. Need to consider the installation location according to the radar test range;
6. In view of the possibility of interference from multiple radars (the possibility of interference from the same frequency for radars), users need to pay attention to the following when installing equipment:
A. It is best to install the radars in the same direction and avoid facing;
B. When three or more radars need to be installed in the same space, the radars should preferably face the same direction, and the distance between the radars should be ≥3 meters;
7. The rotation of large motors such as air conditioners and fans and metal objects blown by the wind will cause false alarms of the radar, and cannot be installed directly facing the air conditioners and fans;
8. The radar needs to be fixedly installed, vibration and shaking will cause the radar to produce false alarms;
9. The radar will detect the occasional movement of pets, birds and other animals. This interference item cannot be eliminated.
