ProductDescription :

Note:

1>.When the radar is working, there should be no metal or other obstructing electromagnetic wave transmission media blocking the antenna in front.

2>.Different shell materials and modules have different distances from the surface of the shell, resulting in different spectral energy and parameter settings that need to be fine-tuned according to actual conditions. It is generally recommended that the module be 5-6mm away from the casing, which can be adjusted based on actual measurement.

3>.It is recommended that users first test according to the default settings of the module. If the effect is not as expected, the shell structural components can be sent to the original factory, which will conduct testing and adjust a reference setting.

4>.The module is used for detecting human movement and presence, so the distance values provided are not precise ranging, only indicating the approximate distance of the target.

5>.If the person being tested sits quietly with their back to the radar, the sensing effect will decrease. Because when facing the radar with the back, the fluctuations in the chest or abdomen caused by breathing cannot be detected.

6>.It is recommended to use plastic or other materials as the outer shell, as radar is a very sensitive module in the human body. If a large attenuation material is used as the outer shell, it may affect the detection.

7>.Avoid air conditioning vents and fan lights during installation.

8>.When multiple modules are installed and used simultaneously, the module spacing should be greater than 0.5 meters, while avoiding antennas from different modules facing each other.

9>.Sensitivity can be adjusted according to user scenarios.
