It uses Doppler radar technology,
With the ability to automatically sensing to control another product, high sensitivity,
sensor distance, reliability, wide-angle sensor,
wide voltage range and other characteristics.
Widely used in lighting conditions, anti-theft alarm.
1. Microwave sensors using a planar antenna and receiving echo.
2. Switch-active sensors.
3. Sensors emit high-frequency electromagnetic waves and receive them for echo.
4. Sensors detect changes within the echo.
5. Sensors detect tiny movement in the detection range.
6. Send the MCU signal and execution instructions.
7. Signals can be detected through the door, glass and thin walls.
8. It will get the best result of the probe if the person or object is moving towards the sensor.
9. This product is a strong protection against interference,
Almost without wind, heat and other external factors.
1. It is better away from the wall about 3-4 meters.
Against receiving a sensor on the other side of the wall;
2. Open areas are more sensitive.
