The principle is to realize the function of the sensor by using the polarization state of light. When a polarized light passes through the medium,
if there is an external magnetic field in the beam propagation direction, the light will rotate an angle through the polarization plane, which is the magneto-optical effect. That is, the applied magnetic field can be measured by the angle of rotation.

The ambient light sensor can sense the surrounding light and tell the processing chip to automatically adjust the current of LED river to reduce or increase the power consumption of LED lamps.
The LED Highbay light, LED Tri proof Battens, LED Floodlight, And LED Streetlight produced by Shenzhen Zisteled technology Co;Ltd, All these function available,
e.g, when the ambient light is bright enough, the use of ambient light sensor can minimize the power consumption of LED lamps to achieve secondary energy saving. On the other hand, ambient light sensors help LED lamps provide a comfortable lighting environment. When the ambient brightness is high, the light sensor will automatically adjust the LED lamp to the appropriate brightness. To ensure that the sum of the ambient light and the light generated by the lamp reaches the originally set brightness.
