Professional Microwave Sensor LED Tube manufacturer: best for car parking lot,stairs,basement,warehouse. When people/car/any object moving, 100% brightness; no movement, can be 1/5%/10%/30%/50% brightness. People can dim the brightness and hold time on the sensor detector by themselves.
Working principle: Doppler radar sensor, so much more sensitive and stable than PIR sensor led tube, and more intelligent！
