Q & A
HW MS03 2.4GHz to 5.8GHz is a compact, low‑cost microwave Doppler radar motion sensor module operating in the 2.4 GHz to 5.8 GHz range. It’s often used in Arduino, ESP8266/ESP32, and other embedded projects
Independent of temperature, humidity, airflow, dust, noise, light and dark, anti-interference, etc. The transceiver module is a field-shaped signal with wide coverage and no blind spots. The induction effect during conduction is better when used indoors.

About false positives:
- To ensure the eligibility of the power supply,
- Test to ensure that the product under test does not surround the moving object (sensing range)
- The power supply initialisation time is about 10s-30s. During this period, it is abnormal sensory, which may cause false-positive artefacts.
- During indoor testing, the sensor is sensitive to the surrounding environment. It needs to remain stationary and ensure that the next cycle step test is performed before the end of the first sensor signal.
- When testing outdoors, pay attention to the dynamic surrounding environment, such as birds. Pedestrians, passing vehicles, etc.
- The signal current output by the module is very weak. It is easy to cause false alarms through the high power of the drive tube.
