HW-MS03 microwave motion sensor module

 Product overview

HW-MS03 The earliest single-board microwave induction module launched by the company, its exquisite appearance, simple and compact product circuit structure, stable performance and cost-effective, its cost-effectiveness is high, especially suitable for intelligent electrical appliances, security products, lighting products, etc. Second development in other electronics fields. This product can be widely used in security monitoring, intelligent control systems, lighting appliances (garages, corridors, roads, etc.).

Product working principle:

HW-MSO3 microwave induction module uses a plane antenna to send and receive high-frequency electromagnetic waves according to the principle of Doppler effects, and then detects that when there is a small movement of the back toll wave, the microprocessor work is triggered. Ping signal.

Product characteristics:

Professional plane micro -band antenna design, field -shaped and receiving signals, covered with wide coverage, high consistency, low power consumption, conforming to ROHS environmental protection, and strong anti -interference ability, not affected by temperature, humidity, air flow, dust, noise, bright and dark and other effects Essence When this product is used in households, the induction effect is better; when used outdoors, the sensitivity distance is slightly reduced or slightly weak due to the influence of the environment. This is a normal phenomenon, and users do not have to question the product.

 Sensing time:

Default can be repeatedly triggered: if the output signal is triggered for the first time, when the inductive area is triggered again, the module delay time will be superimposed again when the first trigger time is not stopped (column: module trigger time is 2s, and accept it within 2S again. When the inductive signal is superimposed again, when it is constantly triggered, there will always be an output signal.) It is not repeatedly triggered: the induction is triggered once, and the time is not superimposed (for example: time 2s, once trigger, output 2s, regardless of whether within 2s, regardless of whether Multiple triggers are deemed to be invalid, and the time is not stacked once to maintain 2s).

 Specifications

Inspection wiring diagram and CAD drawing of the product.

As shown in the figure, VCC power supply+can supply DC-3.7V-24V, JP is the MS03 output port, and 2 outputs a high-level signal in the middle. When pin 2 outputs a high-level signal, NPN tube 8050 conducts, and VCC 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 no signal state of 0V. If you need to test the performance of this product, you can wire it separately according to the above diagram. In the later stage, this signal can be used to trigger: trigger circuit MOS transistor thyristor relay MCU, etc. 

 Angles and Radiation Patterns

As shown in the figure: The reference map is derived from the measuring instrument. The actual sensing area is in accordance with the indoor 100 square meter angle range. Due to the close relationship between Doppler radar microwave and space, the practical application needs to define the detection range and angle according to the application environment (the smaller the microwave detection range space is, the higher the sensitivity is, and the larger the space is, the higher the sensitivity is attenuation). This figure serves as an official guideline for reference. Practical applications need to be checked according to the use environment.

Note:

About the installation process requirements of the product

When installing and testing the product and actual assembly, please be sure to keep at least 10mm in front of the antenna board (S-shaped hole PCB) of the module product. Never touch or touch the plane of any object, or the product will not work properly. 

 About power

It is recommended to use a qualified DC power supply, that is, the output voltage, current and ripple coefficient are all up to the standard DC power supply, otherwise it will affect the stability of the product, there may be some abnormalities, such as: false positives, no induction , Cycle from Kai, etc.

 About false positives

1, to ensure the power of the eligibility, please refer to the above first item;

2. When testing, ensure that there is no moving object (in the sensing range) around the product to be tested.

3,After power on, there will be about 30s initialization time. During this period, it belongs to non-normal induction, which may cause false positives;

4, when the indoor test, the induction is relatively sensitive, the surrounding needs to remain static, and to ensure that the first induction signal cycle is completed after the next test; outdoor test, be sure to pay attention to the dynamic environment of the surrounding environment, such as birds, Pedestrians, traffic, etc.

5. The signal current output by this module is very weak. When the load is directly driven, it may cause false alarms. Please be sure to refer to the application diagram of this product.

 Adjustment of work delay

A [time] resistor is soldered on the back of the module to change the delay time. The larger the resistance, the longer the delay.

 Adjustment of sensing distance

There is a [distance] resistor on the back of the module to change the sensing distance. The larger the resistance, the greater the distance. Adjustable range is 150K-2M.

Note: If the resistance value is greater than 2MΩ, it will make the circuit unstable! Customers are advised not to change this resistor by themselves. If necessary, please contact our relevant staff.

 The shell assembly of this product

The metal shell is not easily penetrated by microwaves and infrared rays, so this product should be avoided from being used in a metal shell. However, barriers such as plastics, ceramics and woody soils have better penetration effects. Specific circumstances, please take the test as the standard.

The product's mutual harmonicity

This product has a certain degree of 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 of results. When necessary, please be sure to contact our relevant staff.
