HW-XC606 Microwave Induction Module

Product Overview

HW-XC606 is the latest dual-board microwave induction module of the company. Its appearance is exquisite, the circuit structure of the product is simple and compact, the performance is stable and cost-effective, and its cost performance is high, especially suitable for other electronic appliances such as intelligent electrical appliances, security products, lighting products, etc. Secondary development of the field. This product can be widely used in security monitoring, intelligent control systems, lighting appliances (garages, corridors, roads, etc.)

Working principle of the product:

The HW-XC606 microwave induction module uses a planar antenna to transmit and receive high-frequency electromagnetic waves based on the Doppler effect principle. When it detects a small movement change in the folded wave, it triggers the microprocessor to work, and finally outputs a 3.3V effective high-level signal from the OUT terminal.

Product features:

Professional 5.8G fixed frequency planar horn antenna design, field shaped signal transmission and reception, wide coverage, high consistency, low power consumption, in compliance with ROHS environmental protection, and strong anti-interference ability, not affected by temperature, humidity, airflow, dust, noise, brightness, etc.

This product has better sensing effect when used indoors; When used outdoors, the phenomenon of slightly reduced sensing distance or weak sensitivity due to environmental factors is normal, and users do not need to question the product.

Induction time:

   Default repeatable triggering: If the output signal is triggered for the first time and triggered again in the sensing area, the module delay time will be added again before the first triggering time stops. (For example, if the module triggers for 2 seconds and receives another sensing signal within 2 seconds, it will continue to trigger continuously for another 2 seconds, resulting in a continuous output signal.)

Cannot be triggered repeatedly: sensing triggers once, time does not overlap. (For example, if triggered once for 2 seconds, the output will be 2 seconds. If triggered multiple times within 2 seconds, it will be considered invalid. If the time is not stacked once, it will remain for 2 seconds.)

Parameter specification:

Inspection wiring diagram and CAD diagram of the product

As shown in the figure, the port is VCC and can supply DC5V. The intermediate output is a high-level signal of 3.3V. When pin 2 outputs a high level, it will supply power to the LED. At this time, the LED is on, indicating that the module has a signal output. When there is no signal output from pin 2, the output terminal is in a signal free state of 0V. If you need to test the performance of this product, you can wire it separately according to the diagram above. In the later stage, this signal can be used to trigger: trigger circuit MOS transistor thyristor relay MCU, etc.

CAD：L23 X M18 X 8mm

Angle and radiation diagram

As shown in the figure, the reference figure is obtained from the measuring instrument, and the actual sensing area is based on the indoor angle range of 100 square meters. Due to the close relationship between Doppler radar microwave and space, the actual application needs to define the detection range and angle according to the application environment (the smaller the space of microwave detection range, the higher the sensitivity,

and the greater the space, the relative attenuation of the sensitivity). This drawing is for official guidance and reference. The actual applicationneeds to be tested according to the use environment.

Product physical drawing:

1. TIME：Default is 2 seconds. If you need to modify it, you can leave a note or modify the resistance yourself.

2. SENS：The default is 10 meters. If you need to modify it, you can leave a note or modify the resistance yourself.

Attention:

1.Requirements for product installation process

During product installation test and actual assembly, be sure to keep at least 10mm space in front of the antenna board (S-shaped perforated PCB) of the module product, and never close to or touch the plane of any object, otherwise the product cannot work normally.

2. About power supply

It is recommended to use qualified DC stabilized power supply, that is, DC stabilized power supply with output voltage, current and ripple coefficient up to standard, otherwise the stability of the product will be affected, and some abnormalities may occur, such as false alarm, no induction, cycle self-start, etc.      

3.About false positives

1. To ensure the qualification of the power supply, please refer to the first item above;

2. During the test, ensure that there are no moving objects around the product to be tested (within the sensing range);

3. There is about 5s initialization time after power-on. During this time, it is abnormal induction, which may cause false alarm; Determined by TIME;

4. In the indoor test, the sensing is relatively sensitive, and the surrounding should be kept static, and the next test should be carried out after the end of the first sensing signal cycle;

During outdoor testing, be sure to pay attention to the dynamic conditions of the surrounding environment, such as birds, pedestrians, vehicles, etc;

5. The signal current output by this module is very weak. When directly driving the load, it will also cause false alarm. Please refer to the application diagram of this product for connection.

4.Adjustment of working delay

There is a 0603RT resistor on the front of the module, which is used to adjust the sensitivity of the sensing distance.

5.Adjustment of sensing distance

There is a 0603RD resistor on the front of the module, which is used to adjust the high-level delay time.

6.Shell assembly of this product

The metal shell is not easy to be penetrated by microwave and infrared ray, so this product should not be installed in the metal shell for use. However, obstacles such as plastic, ceramic and woody soil have good penetration effect. Please refer to the test for details.

7.Mutual harmony of this product

This product has certain mutual resonance interference, so within the effective sensing range, try to avoid installing two or more modules face to face, otherwise, it may affect your use effect. If necessary, please be sure to contact our relevant staff.
