Product Description

1. Product Overview:

HW-M21-2 is the earliest AC load type microwave induction module introduced by our company. It has exquisite appearance, simple and compact product circuit structure, stable performance and cost-effective, high cost performance, especially suitable for intelligent appliances, security products, lighting Second development of products and other electronic fields. This product can be widely used in security monitoring, intelligent control systems, lighting appliances (garages, corridors, roads and other places).
2. Product working principle:
The HW-M21-2 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 slight movement change in the return wave, and then triggers the microprocessor to work. Finally, the AC relay makes 220v / L conduction with AC load circuit to 220v / N.
3. Product Features:
Professional flat microstrip antenna design, field-shaped signal transmission and reception, wide coverage and high consistency, low power consumption, ROHS environmental protection, and strong anti-interference ability, not affected by temperature, humidity, airflow, dust, noise, light and dark.
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 slightly weak. 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 for the first time, 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: Induction triggers once and no time overlaps (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).
