1. Features
This product is a direction-detecting microwave sensor developed based on 24G integrated chips, which candetect approaching signals and ignore away-away signals to shield unnecessary door opening actions. It canalso be switched to bi-directionai detection mode.Compared with the microwave sensor of the module antennaon the market, it has extremely obvious advantages as follows:
Object moving direction recognition: it can accurately judge whether a person or object is approaching ormoving away.
Uper shock resistance: the algorithm can eliminate the reciprocating vibration in a certain range.
Ultra-long detection distance: the maximum detection vehicle can reach more than 8m, and the adult is notless than 5m.
Excellent product consistency:MMlC monolithic microwave integrated integrated antenna ensures that thereceiving sensitivity of each product is extremely close.
2. Internal Structure
Four-core plug-in connector
Sensitivity adjustment knob
MIC integrated planar antenna
Detection direction selection pin header
3. Working Principle
Proximity: Detection is valid Away from: Detect ignore

5.lnstallation Wiring
Install the bottom plate.
Stick the installation template to the appropriate installation position, fix the rubber plug and open the cable holeaccording to the hole position of the template , uncover the outer cover and fix the bottom plate with two matchingself-tapping screws.
Insert one end of the signal line into the connector, and connect the other end to the power supply and controterminals of the automatic door.
1-2 (red and black): Power input 12V-24VAC/DC
3-4 (yellow and white): Signal output COM(normally open)
Power on the sensor, adjust the angle of the panel antenna according to the actual needs of the scene, andadjust the sensitivity to the best effect (reference 5).
Close the outer cover and verify the debugging results.
6.Detection Orientation And Sensitive Adjustment
Detection azimuth adjustment(panel antenna can be adjusted forward, backward, left and right).
Adjust the plane antenna angle to get different detection distances and different detection areas as shown inthe figure below.
Adjust the sensitivity.
MAX: Weaker microwave reflection signal and shorter detection time.
MIN: Stronger microwave reflection signal and longer detection time.
