Description:
microwave sensors using planar antenna and receiving echo. The switch is active sensors and emit a high-frequency electromagnetic waves and receives their echo.
The sensors detect changes within echo and aslo tiny movement in detect range.
Send signal to MCU and execution instruction.
Signals are likely to be detected through the door, glass and thin walls. It will get best probe result if person or object when moving toward the sensor.
This product is a strong anti-jamming capability, almost without wind, heat and other environmental factors foreign interference
