It uses Doppler radar technology, with auto-sensing capabilities to control other product,High sensitivity, sensor distance, reliability, wide angle sensor, Wide supply voltage range and other characteristics. Widely used in lighting situations, anti-theft alarm situations.

Features:

• Microwave sensors using planar antenna and receiving echo.
• The switch is active sensors.
• The sensors emit a high-frequency electromagnetic waves and receives their echo.
• The sensors detect changes within echo.
• The sensors detect 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
