1. Features
Introducing our cutting-edge direction-detecting microwave sensor, expertly developed with 24G integrated chips. This state-of-the-art device discerns approaching signals while adeptly ignoring unwanted signals that would lead to unnecessary door openings. For versatile functionality, it can be conveniently switched to bi-directional detection mode. In comparison to conventional microwave sensors using module antennas, our product boasts remarkable advantages:
Object Moving Direction Recognition: Our sensor excels in accurately determining whether a person or object is approaching or moving away, ensuring precise operation.
Superior Shock Resistance: Our advanced algorithm effectively nullifies reciprocating vibrations within a designated range, enhancing sensor stability.
Ultra-Long Detection Distance: Our sensor achieves impressive coverage, detecting vehicles at distances exceeding 8 meters, and adults at no less than 5 meters.
Unmatched Product Consistency: The MMIC monolithic microwave integrated antenna guarantees that the receiving sensitivity of each unit remains consistently precise.

5. Installation Wiring
Begin with the installation of the bottom plate for a secure foundation.
Adhere the installation template to the selected position, secure the rubber plug, and create a cable opening aligned with the template's hole. Remove the outer cover and firmly attach the bottom plate using two self-tapping screws provided.
Firmly insert one end of the signal line into the connector, connecting the opposite end to the power supply and control terminals of the automated door system.
Connections: 1-2 (red and black): Power Input 12V-24VAC/DC
Signal Output: 3-4 (yellow and white): COM (normally open)
Power the sensor, adjusting the panel antenna's angle to suit the specific scene requirements. Fine-tune the sensitivity for optimal performance (see reference 5 for guidance).
Secure the outer cover and rigorously test the setup to confirm successful debugging.
6. Detection Orientation And Sensitivity Adjustment
Adapt the Detection Azimuth: The panel antenna can be adjusted forward, backward, left, and right for personalized coverage.
Change the plane antenna angle to achieve varying detection distances and areas as depicted below.
Fine-tune the sensitivity setting.
MAX Setting: Results in a weaker microwave reflection signal with a reduced detection time.
MIN Setting: Yields a stronger microwave reflection signal and an extended detection time.
