The HW-MB07 is a cutting-edge single-sided millimeter wave radar sensor module recently launched by our company. It boasts a sleek design, a compact circuit structure, stable performance, and cost-effectiveness, making it an excellent choice for the secondary development of intelligent electrical appliances, security products, and lighting products. This versatile module is widely applicable in security monitoring, intelligent control systems, and various lighting appliances in settings such as garages, corridors, and roads.
The HW-MB07 millimeter wave induction module operates using a plane millimeter wave horn antenna to transmit and receive high-frequency electromagnetic waves based on the principle of the double-transmitter horn Doppler effect. Upon detecting subtle movement changes in the backscatter wave, it activates the microprocessor, resulting in a 3V effective high-level signal output from the OUT terminal.
Featuring an MCU fixed frequency 10.525G millimeter wave horn antenna design, the module delivers a field-shaped transceiver signal with broad coverage, high consistency, and low power consumption. It meets certification standards such as ROHS, CE, KC, and UL, showcasing robust anti-interference capabilities unaffected by environmental factors like temperature, humidity, airflow, dust, noise, light, and darkness.
The high-frequency millimeter wave 10.525G ensures precise detection and exceptional anti-interference capabilities against technologies like WIFI, Zigbee, Bluetooth, and various frequency bands. It is well-suited for a wide range of intelligent product development applications. While indoor usage provides optimal sensing performance, outdoor use may slightly impact sensing distance or sensitivity due to environmental influences, which is a normal operational characteristic.
The module offers two induction time options:
Default Repeatable Trigger: The module delay time is superimposed if the output signal is triggered multiple times within the sensing area without interruption.
Non-Repeatable Trigger: The induction is triggered once, and the time is not superimposed, ensuring a consistent output duration regardless of repeated triggers within a specified timeframe.

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
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.

1. TIME defaults to 2 seconds and cannot be customized. If you need to change it, please contact our technical staff.
2. The SENS potentiometer rotates clockwise, the shorter the distance, the counterclockwise, the longer the sensing distance. (SENS potentiometer rotates clockwise, the sensitivity decreases, and counterclockwise, the sensitivity increases.)
3. If no potentiometer is needed, please contact our company's technical staff, there is a reserved patch resistance adjustment method in the circuit position.
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.
