According to the Doppler effect principle, the HW-XC508 microwave sensing module uses a planar antenna to transmit and receive high-frequency electromagnetic waves, and then detects a slight movement change of the folded-back wave, which triggers the microprocessor to work. Finally, the OUT output is 5V. High level signal.
Professional 5.8G fixed-frequency plane horn antenna design, field-shaped transceiver signal, wide coverage, high consistency, low power consumption, ROHS-friendly, and strong anti-interference ability, free from temperature, humidity, airflow, dust, noise, bright Dark and other effects.
When the 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 due to the influence of the environment. This is a normal phenomenon, and the user does not have to question the product.
The default repeatable trigger: after the first trigger output signal, when the sensing area is triggered again, the module delay time will be superimposed again when the first trigger time is not stopped (for example, the module trigger time is 2S, and it is accepted again in 2S). The sensing signal is superimposed 2S again, and there will always be an output signal when it is continuously triggered without interruption. Non-repeatable triggering: The sensor is triggered once, and the time is not superimposed (for example: time 2s, trigger once, output 2s, no multiple triggers are considered invalid within 2s, time is not superimposed once for 2s)
