Output models Category: Digital sensor
How it works: vibration sensor
Sensor Type: 2.4GHz to 5.8GHz radar sensors
1. Independent of temperature, humidity, airflow, dust, noise, light and dark and other effects, anti-jamming;
2. The microwave transceiver module is a field-shaped signal, wide coverage and no blind spots;
3. During transmission of microwave induced effect is relatively good: when used indoors, the better
Recommends qualified DC power supply, that is, the output voltage,
current and ripple factor are all standard DC power supply, otherwise Movies
Rang stability of this product, there may be some exceptions,
such as: false, no newspaper, circulating auto-start, and so on.
About false positives
1, to ensure the eligibility of the power supply, please refer to the first item;
2, the test to ensure that the products being tested are not surrounding a moving object (sensing range);
3, approximately 10s-30s after power initialization time,
during this period are non-normal induction, may cause false positives false image;
4, when tested indoors, the sensor is relatively sensitive to the surrounding need to remain static,
and to ensure that the end of the first sensor signal before the next cycle
Step test; outdoor test, be sure to pay attention to the dynamics of the surrounding environment,
such as birds, pedestrians, passing cars and the like;
5, the signal current of the module output is very weak,
high-power direct drive through the drive tube, it may easily lead to false positives.
This product is a housing assembly
Metal microwave can not easily be penetrated,
so this product should be avoided for use in a metal enclosure.
However, if the barrier plastics, ceramics, wood earthy
Was penetrating effect is better. Specific cases, to test subject.
The product of the cross harmonic
This product has a mutual interference of resonance,
it is within the effective range of the sensor, avoid installing two or more modules, otherwise, their mutual Interference may affect your results.
