High Performance Motion Sensor HW-MS03 2.4GHz to 5.8GHz Microwave Human Body Induction PIR Module for Diy

High Performance Motion Sensor HW-MS03 2.4GHz to 5.8GHz Microwave Human Body Induction PIR Module for Diy Beskrivelse

Features: 1. Independent of temperature, humidity, airflow, dust, noise, light and dark, anti-interference, etc.
2. The transceiver module is a field-shaped signal with a wide coverage and no blind spots.
3. Microwaves have relatively good induction effects during transmission: when used indoors, the effect is better; When used outdoors, there may be a slight decrease in sensing distance or sensitivity due to environmental factors. This is a normal phenomenon, users need not doubt it.
About electricity: It is recommended to use a qualified regulated power supply, that is, a regulated power supply with qualified output voltage, current and ripple factor, otherwise it will affect the stability of this product and may cause some abnormalities, such as: false alarm, no alarm, self-start of cycle, etc.
About false positives: 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 is about 10s-30s. During this period, it is abnormal sensory, which may cause false positive artifacts.
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.
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.
6. This product is a housing component and the metal is not easily penetrated, so this product should not be used in metal housings.
note:The printing/appearance may vary from batch to batch, but will not affect the use
