HW-N9MW microwave sensor module
Based on the Doppler, HW-N09 microwave motion module can output the useful controllable electrical signals after triggering the microprocessor to work once detected the changeable of reflected wave with the planar antennas which can transmit and receive the HF electromagnetic wave. The module is wildly used in security monitor, smart control system,illuminative light etc.
- No affected by temperature, humidity, airflow, dust, noise, light, dark and other factors because of its stronger anti-interference capacity.
- Wide coverage without blind zone because of its field pattern emission.
- The sensitive of the product indoor is better than outdoor’s because the microwave is easier to reflect on the transmission
- Professional design of the microwave with flat antenna, low-power, ROSH and high product consistency.
3. Specification：（Regular ）
- Voltage, current, distance, time and size can be customized.
- Customized distance ranging from 1-20m; customized time ranging from 0.1-2000s. Others can consult our engineers.
|Remark||3.The module has reserved CDS photo-resistance port that can be used in light control|
|function. The default is “Repeat Triggering ”|
|4.We suggest that you should use our regular products because we would charge extra fee|
|on some customized projects. More details could talk with us.|
It is suggest that you should use qualified DC regulated power supply which the output voltage,current and ripple coefficient are standard. Otherwise, it could reduce stability like misreported,unreported, cycled auto start.
1、 Ensure qualified power. See notice 1
2 、Ensure there isn’t moving object around the tested products.
3、 It doesn’t detect and may cause misreported during starting up 10s-30s after electricity.
4 、 The sensitive is higher when testing indoor. Please keep quiescent state and test the second after finishing the first detected signal.Pay more attention to surroundings when testing the module outdoor.Like flying bird,walking man,running vehicle etc.
5 、 The output signal current of the module is too weak so that it may easier to make misreport when working high-powered device.
● Time Adjusting
There is time resistance on the back that you can adjust time.The higher resistance is,the longer time is.
● Distance Adjusting
There is distance resistance on the back that you can adjust distance.The higher resistance is,the longer distance is.
Notice: Circuit would become instability when the resistance is greater than 3 MΩ.It is kindly suggest that customers shouldn’t adjust the resistance. Please contact us if needed.
The module should avoid installing into metal shell because it isn’t easier to penetrate metal shell. The penetrating is better for plastic,china,wood and soil. Please see the standard after testing for specific case.
The module has interfering for each other. Therefore,within the scope of effective induction, please avoid installing two or more modules on one product. otherwise, the mutual interference may affect the use effect for you. Please contact us if needed.
