10.525G HW-MB07 millimeter wave radar sensor module

2.Working principle of the product:

The HW-MB07 millimeter wave induction module uses a plane millimeter wave horn antenna to transmit and receive high-frequency electromagnetic waves according to the principle of double-transmitter horn Doppler effect. When it detects that there is a slight movement change in the backscatter wave, it triggers the microprocessor to work, and finally outputs a 3V effective high level signal from the OUT terminal.

3.Product features:

MCU fixed frequency 10.525G millimeter wave horn antenna design, field shape transceiver signal, wide coverage, high consistency, low power consumption, in line with ROHS.CE.KC.UL and other certification requirements, and strong anti-interference ability, not affected by temperature, humidity, airflow, dust, noise, light and dark.

High frequency millimeter wave 10.525G has high detection accuracy and special anti-interference ability for special WIFI · zigbee 1 · BT · 2.4G · 5G, etc. It can better adapt to most applications of secondary development of intelligent products. When the product is used indoors, the sensing effect is better; When used outdoors, the sensing distance is slightly reduced or the sensitivity is slightly weak due to the influence of the environment. This is a normal phenomenon, and users need not question the product. This product is mostly used in macro scenes.

4.Induction time:

Default repeatable trigger: if the output signal is triggered for the first time and triggered again in the sensing area, the module delay time will be superimposed again when the first trigger time is not stopped (for example, the module trigger time is 2S, the sensing signal is received again within 2S, and then superimposed again for 2S, and there will always be output signal when the trigger is continuously triggered).

Non-repeatable trigger: the induction is triggered once, and the time is not superimposed (for example, the time is 2s, the trigger is once, and the output is 2s. No matter how many triggers are considered invalid within 2s, the time is not superimposed once, and the time is kept for 2s).

6.Inspection wiring diagram and CAD diagram of the product

As shown in the figure, VCC can supply DC5V, JP is the MB07 output port, 2: the middle output high level signal is 3V, when the two pins output high level, the LED is on, at this time, the LED is on, indicating that the module has signal output. When there is no signal output at pin 2, the output terminal is 0V without signal. If the performance of this product needs to be tested, it can be wired separately according to the above figure. Later, the signal can be used to trigger: trigger circuit - MOS tube - thyristor - relay - MCU, etc.

7. 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.

9.Attention: 

9.1 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.

9.2 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.      

9.3 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.

9.4 Adjustment of working delay

A [time] resistor TIME is welded on the front of the module to change the delay time (Please contact relevant staff if VR is not required).

9.5 Adjustment of sensing distance

There is a [distance] resistor SENS on the front of the module to change the inductive distance (If VR is not required, please contact relevant staff.

9.6 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.

9.7 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.
