    The SY22306-S1 is an ambient light sensor (ALS) with SMBus-compatible I2C interface. Communication to the device is accomplished through the fast I2C interface (up to 750 kHz) for easy connection to a microcontroller or embedded controller.

    The ambient light sensor (ALS) has five operating ranges for adapting to different applications and various optical arrangements. The ALS reading (output data) is proportional to the ambient light; no additional data manipulation is required. It also has a built-in circuit to reject the flicker noise caused by indoor light sources. The most important feature of the ALS is that the spectral response is almost the same as the human eye’s photopic vision due to a well-engineered optical coating on the top of the photodiode; thus, a light source correction coefficient is unnecessary.
