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/x27;s eye, door lock, low-power camera, etc 5. Wide application range Parameters: Operating frequency: 10.525GHz (10.40/10.65GHz) Working voltage: 3.3/12.0V Working current: 16mA (Max, VCC=3.3/12.0V) Detection angle: ceiling mounted/3dB beam width/110 ° ± 10 ° Sensing distance: 2/8 meters (hanging height: 3 meters) Output voltage: 3.3V (3.2/3.4V)
