HW-AC100 The earliest AC load-type microwave induction module introduced by our company, its exquisite appearance, simple and compact product circuit structure, stable performance and cost-effective, its cost performance is very high, especially suitable for intelligent appliances, security products, lighting products, etc. Secondary development in other electronics fields. This product can be widely used in security monitoring, intelligent control systems, lighting appliances (garages, corridors, roads and other places).
Product working principle:
The HW-AC100 microwave induction module uses a planar antenna to transmit and receive high-frequency electromagnetic waves based on the Doppler effect principle, and then detects a small movement change in the return wave, and then triggers the microprocessor to work. Finally, the AC relay makes the 220v / L guide Pass band AC load circuit to 220v / N.
3. Product Features:
Professional flat micro-strip antenna design, field-shaped signal transmission and reception, wide coverage, high consistency, low power consumption, ROHS environmental protection, and strong anti-interference ability, not affected by temperature, humidity, airflow, dust, noise, light and dark, etc. .
When this product is used indoors, the sensing effect is better; when it is used outdoors, the sensing distance is slightly reduced or the sensitivity is weak due to the influence of the environment. This is a normal phenomenon, and users do not have to question the product.

5. Induction time:
Default repeatable trigger: If the trigger signal is triggered again in the sensing area after the first trigger, the module delay time will be superimposed again when the first trigger time is not stopped (such as: the module trigger time is 2S, and it will be accepted again within 2S) To the induction signal, superimpose 2S again, and there will always be an output signal when triggering continuously. Non-triggerable triggering: Inductive trigger once, no time superimposed (such as: time 2s, trigger once, output 2s, within 2s) Regardless of multiple triggers are considered invalid, the time is not superimposed and maintained for 2s.
6.Product wiring diagram and CAD drawing
As shown in the figure, for AC100, the red wire is connected to 220v / L, the black wire is connected to 220v / N, the green wire is connected to one end of the AC load, and the yellow wire is connected to the other end of the AC load. The sensor will be in the working state. The internal relay K will conduct the RL (LOAD) circuit to N, so that the light bulb is in a light-emitting state. If you need to adjust the distance and time, you need to power off first, and then adjust the adjustable resistor on the back of the module according to regulations.
7. Angle and radiation pattern:
As shown in the figure: The reference diagram is obtained by the measuring instrument. The actual sensing area is based on the indoor 100 m2 angle range. 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 microwave detection range, the higher the sensitivity, and the larger the space, the sensitivity will be relatively attenuated). This picture serves as an official guide and reference, and the actual application needs to be tested according to the use environment.
