    The SQ81137AS22-J00 is an industrial-grade ambient light sensor. It features two photodiode arrays manufactured through different coating processes to sense ambient light. Both channels output ADC counts proportional to external irradiance intensity. The ALS channel, coated to sense visible light, is typically used to calculate the lux level. The CLEAR channel is used for lux calculation compensation, enhancing lux calculation accuracy in various ambient light environments.

    The SQ81137AS22-J00 design features high performance, high data uniformity, low data noise, a user-friendly interface, and high reliability. These features make it suitable for industrial applications requiring ambient light sensing.
