Chip internal integration algorithm, direct output detection results, without the need for external microcontroller. Module pulse power supply mode, power consumption in the microamp level, mainly for low-cost, low-power applications 4. Embedded installation, not affected by temperature and humidity, soot, water mist, etc., can be applied to all kinds of lamps and lanterns, such as bulbs, downlights, ceiling lights, etc. Low-power application scenarios, such as visual doorbell, cat s eye, door lock, low-power cameras, etc. 5. Wide range of applications Parameters. Driving power supply design considerations. Be sure to use a drive power supply with output voltage, current and ripple coefficient that meet the standard. Unstable drive power supply and too strong electromagnetic radiation will cause false alarm of radar module, no perception, cyclic self-start and other phenomena. The matching drive power supply should be 3.3~12V, the drive current should not be less than 1mA (or 100mA), the power ripple amplitude needs to be controlled within 100mV, and the industrial frequency fluctuation amplitude should be small. Drive power supply and radar module assembly, should avoid the radar module bottom or antenna surface, facing the drive power module, and should be as far as possible from the drive power module inside the rectifier bridge, switching transformer and other industrial frequency interference Large interference devices to prevent interference with microwave signals. Caution: The device equipped with radar module, the installation location should be far away from ventilation ducts, fire ducts, drainage ducts, mechanical vibration or large metal equipment and other strongly vibrating objects, because it will affect the radar reflected waves and detection and perception effect. It is strictly forbidden to work with electricity, in order to avoid action error, wrong connection, burned circuit or electric shock. Avoid installing in the place of sun and rain to prevent damage and affect the service life. The device must be installed in a place far from the electromagnetic field, so as to avoid electromagnetic interference to produce false action; also to be installed in a place far from the fixed rotation or swing of objects (such as electric fans, swinging leaves, drying clothes in the wind It should also be installed away from places where objects are fixed or swinging (e.g. electric fans, swinging leaves, clothes drying in the wind, etc.) to avoid false movements. Several built-in radar module devices fixed installation, should ensure that the distance between each device ≥ 0.5m. Radar module antenna surface is recommended to be 3~5mm from the product shell, otherwise it will affect the perception distance. After the built-in radar module of the device, it is recommended to be placed 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 built-in radar module devices (such as lamps and lanterns) near, there are other light objects (such as emergency lights, guide lights and other interference light source), so as not to cause the device (lamps and lanterns) built-in light-sensing (if any) judgment failure, so that the device (lamps and lanterns) can not work properly (often extinguished, misjudged as daytime). The use of built-in radar module devices (such as lamps and lanterns) if they have been working (always on), can not be based on the detection of moving targets on and off, it may be the radar module by medium frequency interference, resulting in the module has been judged to have moving targets in the sensing range of activities. At this time, the power should be turned off, check whether the power supply status of the power board is normal and whether the module spatial distance has changed. If the above problems can not be solved, please first power off and observe the situation around the installation location, first exclude the influence of the surrounding environment interference factors; restart the power supply and still have problems, then consider replacing the device drive power supply
