Precautions

• Ensure the sensor's antenna is directly facing the detection area, and the surrounding space is open and unobstructed.
• The installation position of the sensor must be secure and stable, as sensor movement will affect detection accuracy.
• Ensure there are no moving objects or vibrations behind the sensor. Since radar waves can penetrate objects, the rear lobe of the antenna may detect movement behind the sensor. To mitigate this, use a metal shield or metal backing to block the rear lobe and reduce the impact of objects behind the sensor.
• If there are multiple 24 GHz radars in the working environment, avoid having their beams face each other, and install them at a distance to minimize potential interference.
• The power input voltage range is 3.0V~3.6V, with no significant spectral peaks in the power ripple within 2MHz. This solution is provided as a reference, and users should consider appropriate electromagnetic compatibility designs, such as ESD protection and lightning surge protection.
