Microwave Sensor/Radar Detector for Automatic Doors

Product Description

1. Introduction
This product is the direction detection microwave sensor based on 24G integrated chips. It detects the approach signal, ignores the far away signal and shields unnecessary door opening actions. It can also be switched to two-way detection mode. Compared with microwave sensors with modular antennas on the market, it has extremely obvious advantages as below:
2. Why choose our microwave motion detector?
1) Object movement direction recognition: It can accurately judge whether a person or an object is approaching or far away. 2) Super anti-vibration: The algorithm can eliminate reciprocating vibrations in a certain range. 3) Ultra-long detection distance: The maximum detection distance of vehicle can be up to 8 meters or more. For adults, it is not less than 5 meters. 4) Excellent product consistency: MMIC monolithic microwave integrated antenna ensures that the receiving sensitivity of each product is very close.

6. Troubleshooting

Failure	Possible Reasons	Solution
No action	Input voltage does not meet the requirements.	Replace the power supply.
	Poor contact or wrong wiring.	Check wires and terminals.
Abnormal action	The sensor housing is covered by dirt.	Clean the surface.
	Sudden changes in the environment in the detection area.	Check installation and site environment.
Unexplained action (repeated)	There are moving objects in the detection area.	Remove the object.
	There are water drops on the mask.	Remove water droplets.
	The installation surface shakes a lot.	Re-fix the mounting surface.
	The detection area overlaps the door body.	Adjust the sensor angle to keep it away from the door.
