【HW-MS03】HW-MS03 Microwave Radar Motion Sensor Module 2.4GHz to 5.8GHz.Output category: digital sensor; Working principle: vibration sensor; Sensor type: 2.4GHz to 5.8GHz radar sensor; Material: mixture., 【Specification】Independent of temperature, humidity, airflow, dust, noise, light and dark, anti-interference, etc. The transceiver module is a field-shaped signal with a wide coverage and no blind spots. The induction effect during conduction is better: better when used indoors. Recommended qualified power supply, ie output voltage, current and ripple factor are standard power supplies, otherwise it is a movie., 【About false positive】1. To ensure the eligibility of the power supply, please refer to the first item. 2. Test to ensure that the product under test does not surround the moving object (sensing range) 3. The power supply initialization time is about 10s-30s. During this period, it is abnormal sensory, which may cause false positive artifacts., 【About false positive】4. During indoor testing, the sensor is sensitive to the surrounding environment and needs to remain stationary, and ensure that the next cycle step test is performed before the end of the first sensor signal. When testing outdoor, be sure to pay attention to the dynamic surrounding environment, such as birds. Pedestrians, passing vehicles, etc., 【About false positive】5. 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. This product is a housing component and the metal is not easily penetrated, so this product should not be used in metal housings.
