Rain light sensor
Product Overview
The rain and light sensor is a core component of the automotive intelligent control system, suitable for various passenger and commercial vehicle scenarios. It can accurately detect the external rainfall volume and ambient light intensity, and automatically control the wiper operating frequency and the on/off state of vehicle lights. It needs to have high detection accuracy, fast response, high/low temperature resistance and electromagnetic interference resistance to adapt to the vehicle-mounted environment.
