Overview
BX-051-I4K is based on the photoelectric principle of semiconductors, which can be used to detect changes in external ambient light. It contains a photosensitive device that converts the light signal into an electrical signal. When the ambient light is too strong or too weak, the microcontroller inside the sensor determines whether the conditions for turning on/off the lights, and communicates with the vehicle to control the turning on/off of the lights. The sensor integrates light acquisition, signal processing, communication output, algorithm and other modules. It has the advantages of small volume, fast reaction and low power consumption.
