Features:
1. Use high-quality materials with guaranteed quality
2. The low-power micro/motion sensing module is designed based on the X-band radar chip, and the center frequency is 1 0.525GHz. The design adopts fixed frequency, directional transmitting and receiving antenna (1T1R), integrates IF demodulation, signal amplification and digital processing functions, has the ability of delay setting, and is convenient to adjust parameters independently, and has the advantages of no wall penetration, anti-interference, small size, good clutter and high harmonic suppression effect, high stability and consistency
3. The algorithm is integrated inside the chip, and the detection results are directly output, without the need for an external single chip computer. Under the module pulse power supply mode, the power consumption is at the microampere level, mainly for low-cost and low-power applications
4. Embedded installation, not affected by temperature and humidity, oil smoke, water mist, etc., can be applied to various lamps, such as bulb lamp, down lamp, ceiling lamp, etc. Low-power application scenarios, such as visual door bell, cat's eye, door lock, low-power camera, etc

Precautions for design of drive power supply:
Be sure to use the drive power supply with the output voltage, current and ripple coefficient up to the standard. The unstable drive power supply and strong electromagnetic radiation will cause the false alarm of the radar module, no perception, cycle self-start and other phenomena;
The supporting driving power supply shall be 3.3~12V, the driving current shall not be less than 1mA (or 100mA), the power ripple amplitude shall be controlled within 100mV, and the power frequency fluctuation amplitude shall be small;
When assembling the drive power supply and the radar module, avoid the bottom of the radar module or the antenna surface, face the drive power supply module directly, and try to keep away from the rectifier bridge, switch transformer and other power frequency interference in the drive power supply module
Disturbing devices to prevent interference with microwave signals.
matters needing attention:
Devices equipped with radar modules should be installed far away from places with strong vibration objects such as ventilation pipes, fire pipes, drainage pipes, mechanical vibration or large metal equipment, because it will affect the radar reflection wave and detection perception effect;
Live working is strictly prohibited to avoid action error, wrong connection, burning circuit or electric shock;
Avoid installation in the sun and rain to prevent damage and affect the service life;
The device must be installed away from the electromagnetic field to avoid misoperation caused by electromagnetic interference; It should also be installed away from the fixed rotation or swing of objects (such as electric fans, swaying leaves, drying clothes in the wind
To avoid misoperation;
When several built-in radar module components are fixed, the spacing between components shall be ≥ 0.5m;
The antenna surface of the radar module is recommended to be 3~5mm away from the product shell, otherwise the sensing distance will be affected;
After installing the built-in radar module, it is recommended to place it horizontally or vertically within the effective sensing range, and try to avoid installing two or more built-in radar module devices face to face;
Avoid other illuminants (such as emergency lights, pilot lights and other interfering light sources) near the devices (such as lamps) with built-in radar modules, so as to avoid the failure of the judgment of the built-in light sensitivity (if any) of the devices (lamps), and make the devices (lamps) unable to work normally (normally off, misjudged as daytime);
If a device (such as a lamp) that uses a built-in radar module has been working (always on) and cannot be turned on or off according to the detection of moving targets, it may be that the radar module has been subject to intermediate frequency interference, causing the module to always judge that there are moving targets moving within the range of perception. At this time, turn off the power supply and check whether the power supply status of the power board is normal and whether the module space distance changes;
If the above problems cannot be solved, please cut off the power and observe the surrounding conditions of the installation location first, and eliminate the influence of surrounding environmental interference factors first; If there is still a problem after restarting the power supply, consider replacing the drive power supply of the device
Re-verify the board or radar module.
