HW-N9MW The company launched the first dual-plate microwave sensor module, its appearance is beautiful, the product circuit structure is simple and compact, stable performance and affordable, its cost-effective and high, especially suitable for intelligent appliances, security products, lighting products and other Secondary development in the field of electronics. This product can be widely used in security monitoring, intelligent control systems, lighting appliances (garage, corridors, roads and other places).
2. Product working principle:
The HW-N9MW microwave sensor module uses a planar antenna to send and receive high-frequency electromagnetic waves according to the principle of Doppler effect, and then detects micro-movement of the folded wave and then triggers the microprocessor to work. Finally, the OUT terminal outputs 3V effective high-power. Flat signal.
3. Product features:
Professional planar microstrip antenna design, field-shaped transmission and reception signals, wide coverage, high consistency, low power consumption, ROHS environmental protection, and strong anti-interference ability, not affected by temperature, humidity, air flow, dust, noise, light and dark . When the product is used indoors, the induction effect is better; when used outdoors, due to the influence of the environment, there is a phenomenon that the sensing distance is slightly reduced or the sensitivity is slightly weaker. This is a normal phenomenon, and the user does not need to question the product.
4. Induction time:
The default repeatable trigger: If the trigger signal is triggered again in the sensing area after the first trigger of the output signal, the module delay time will be added again when the first trigger time is not stopped. (For example, the module trigger time is 2S, and it is accepted again in 2S. To the sensing signal, once again superimposed 2S, there will always be an output signal when there is no nonstop trigger.) Non-repetitive trigger: The sensor triggers once, no time superimposed (for example: time 2s, trigger once, output 2s, within 2s Regardless of multiple triggers as invalid, time does not stack once for 2 seconds.
